I'm hoping that even though there are a good number of posts listed, it is still a small percentage of the total number of vettes in this forum....
Any other tips I should know besides putting it in reverse when parked?

First thing I'd do is check the clutch fluid. Second thing is warm the oil to over 100 and see if the shifting action under power is free of grinding sounds. Then I'd repeat the test with shifts over 5500. Absence of grinding is a good sign.

tips for newbie
Thanks Ranger.
I guess it's a good thing that I'm getting the extended warranty!! Should I have someone make sure the clutch is properly adjusted or is this something I don't have to worry about?

Regarding the clutch, there are no easy ways to adjust it. But....
Better start checking and changing the clutch fluid if you're running the stock Z06 clutch.
To do that check the fluid in the clutch master cylinder (reservoir). You'll probably find some black nasty fluid that's been cooked from heat. The stock clutch in the LS1/2/6/7 all can suffer from pedal woes if the clutch fluid is allowed to degenerate.
More clutch fluid details are here and here.
Gotta be careful if the clutch pedal begins to act up. It can lead to missed shifts due to an incomplete clutch disengagement. That, of course, is a direct path to tranny issues.

Extended Warranty
I'm getting the warranty through my credit union. I don't remember the name off hand but they said the company has been around for many years and have taken good care of members.
I will check the clutch fluid and have it flushed if needed. I just flushed the power steering, brake and tranny fluid in my truck.
What would you recommend for motor oil?
I used Amsoil in my harley and it actually ran 15 degrees cooler and seemed to have a bit more zip. After 6,000 miles it came out like new. My buddy said it's because amsoil doesn't clean the engine, but I was told it's because the oil doesn't burn or break down which is what turns oil black.
I love that BS smiley. Could have used that in the motorcycle forum.
Thanks,
Dan

I am the second owner of a 2002 Z06, 17,000 miles. 2nd gear feels just a little "off" when downshifting. Guessing it is indeed a syncro. Do you guys know if this is something that would be fixed with the recall even though I am 2nd owner and it is past the 3 year part of the warranty?

Corvette C5 AMSOIL Series 2000 0w30 Used Oil Analysis Report
In this report the 6/24 and 5/6 samples were AMSOIL Series 2000 0w30, the 3/11 sample was German Castrol 0w30. Compare the levels of Magnesium (a detergent/dispersant) in the AMSOIL to the German Castrol and to the universal averages for the lab. It is about double the average.
AMSOIL may come out very dark on the first oil change as it cleans out the engine, but likely will be lighter after that as it keeps the engine clean.
The LS6 takes an oil meeting GM Standard 4718M. These AMSOIL synthetics meet this standard:
AMSOIL Series 2000 0w30
AMSOIL SAE Synthetic 10w30
AMSOIL SAE Synthetic 5w30

Most trannies are a bit stiff until warmed up (oil temp >100). Once warm though, the tranny should be smooth but still notchy through the shift gates.
My trannies have been perfect through 500+ passes in three Z06s. But I help that along by
(1) changing the tranny fluid at 18K intervals,
(2) taking good care of the clutch, and
(3) not missing shifts.
So, you might want to change the tranny fluid and see if it helps your second gear issue.

If anyone has some insight please fill me in.

This typically would be a warranty only repair. And it gets 14 hours of labor plus parts, so plan on spending some $$$.

You can save yourself alot of time,money and most of all headache and do it right the first time. g force transmissions sells a kit with hardened shafts , gears , sincro assembly , the works. Im blown with nos 640rwhp shifts great no problems anymore. Spent $1,800 in parts fixing problems some 2 times. $3,000 with all new g force parts no issuesanymore i can shift hard and not have to worry about it. These problems started with just a 100hp nos shot , i did the tranny when i installed the blower. And the t56 is super easy to rebuild.

Got my GMPP
I purchased my GMPP today, I was gearing towards the 36/36K/100deductible, however Dennis at Fitchner Chevrolet said that since I don't drive my car but about 8-9K per year I should go with the 48/32K/100 and get an additional year but loosing 4K miles. Seeing how I really don;t drive it more than that it really made better sence to get the additional year. Besides I saved myself a Whopping 15$ selecting the 48 month plan. 
The Key to this whole thing is getting the GMPP while your GM warranty is still intact, and your car is under 24K miles!!!
to all!!

Pop out of first gear
A couple times in the last few days the car has popped out of first gear when taking off from a start. I've only had the car a week.
Has anybody had this problem? Am I not getting it completely in gear or is this a sign of a potential problem.
My first guess is that it's going to be a problem. Glad I bought the extended warranty.
