At the red arrows. You should use the jack pucks:
The red arrows indicate the frame contact hoist locations, and optional vehicle jacking locations. The jack stands will not be in your way.

No, those are for flat changing
If you're going to put the car up on jacks, you need to use the "Preferred Jack Points" Here is excellent post that will show you the correct points.

IMO if you're going to work on your car with any regularity, short of having a home lift, buy a quality floor jack (or two); Northern Tool adaptor beams and jack stands. I feel safest under the car with floor jacks/adaptor beams under the preferred jacking locations and having jack stands under the frame rail shipping slot reinforcements.
Here's a great alternate method:

You're correct...there are 1) preferred jacking locations 2) optional vehicle jacking locations 3) frame contact hoist locations, optional vehicle jacking locations and 4) suspension contact hoist locations.
The service manual says when using a "Suspension Contact Hoist...position the (suspension contact) front lift under the outer edge of the front suspension lower control arms. Position the (suspension contact) rear lift under the rear tire and wheel assemblies."

Hey guys, thanks for "plugging" my 4-point jacking post 
http://forums.corvetteforum.com/show....php?t=1301555
Only problem... when doing exhaust or differential work, placing a jack / stands under the rear-most "preferred" jacking points does not allow easy access to what you're working on. In these cases, what I do is first jack up the entire car using my 4-point method, then place good heavy-duty jack stands under the rear puck locations (using pucks of course), then remove the rear jack from the "preferred" area. But then, I'll put some screw jack stands back under the "preferred" points of extra safety (hydraulic bottle jacks would work well here too)... if and when these screw jack stands get in the way during the job, I just pull 'em out temporarily, then replace.
I'm using heavy-duty 7-ton forklift jack stands under the rear puck locations... on flat concrete:

This photo from my differential fluid change post illustrates what I describe above:
Of course, some will consider this overkill, but for me, there is no such thing as overkill when I'm laying under something that weighs over 3,000 pounds.

Safety
Great advice . . .I think the professionals know the routine since safety's a part of their work process every day.
Those of us weekend wrench-turners that might know enough to be dangerous are the ones that invariably are injured by taking unnecessary risk or simply not knowing any better.
Unlike some of the repetitive posts that we see every week, this message about safety cannot be stressed enough IMO.
Thanks and best wishes-

There are several garages in our area that will rent their drive on lift at a resonable hourly rate. If I were going to do a DIY exhaust mod I would seriously think about going this route before I would buy all that equipment. Plus I still would not feel comfortable or safe, under the car. IMHO, a drive on ramp with safety pins in place is by far, the safest and easiest route.

i have been working on my c6 for over 2 years now and i usually put the jack stands under the leaf springs. they were obviously made to support the weight of the car. remember this is a car not a piece of jewelry.

In sum, if you are jacking / supporting the car in any way NOT recommended by the manufacturer, you are taking a risk of either damaging the car or possibly getting severely injured.
Don't want to sound like a nanny... but after all, how hard is it to simply follow the manufacturer's instructions?????
If jacking / supporting is too much of a bother, just get some Race Ramps.
For a big job though, I agree with VettinFan's recommendation of trying to rent a professional drive-on lift... this will be SAFE and will make the job as easy as possible to execute.

I use a pump jack at each end with a crossbeam adapter attached. I modified the cross beams so my floor jacks fit securely at the outer ends...no chance of slippage.
I installed an aftermarket cat-back with this set-up and had no problem with them being in the way.
