CAI reality
I'm hoping that K&N will be making drop in filters for the 08's.

yes, provided it's not an '08 (the '08 uses the z06 style air ducting/filter).
depending upon how much you want to do, here's a list of some basic airbox mods.
1. remove the rain guard (the plastic piece that covers both filters)
2. cut off the tops of the filter boxes.
CAUTION either one of the above two can lead to engine failure. the rain guard prevents the air boxes from filling up with water. if the rain guard is removed water can and will pass through the filters and collect in the boxes, just waiting to be sucked up into the engine.
3. remove the air box tops. move the left box to the right side and the right box the the left side. turn the box upside down, so the filter is facing the ground. insert the filter box into the duct/airbridge (upside down). outline the airboxes. remove the boxes and cut the shroud, following the outline. reinstall the airboxes (left on right side, right on left side, filters facing the ground through the holes in the shroud). seal the opening.
this works well, but requires aftermarket filters (the paper ones won't last long) and is a pita to check/change the filters.
Mostly the exhaust, headers to the tailpipe preferred. If you beef up one end you should balance the other so they work together.
Rule of thumb: What goes in must come out!

Not sure how something like the K&N would do as compared to option 1 above. The twin snout K&N in chrome really does look good.
I have not driven in the rain, so I can't say.

Get a black rectangular office type plastic trash can (5 bucks at Lowes). Cut it in half so you have about 10 inches of the the bottom part, then cut that piece in half so that you have a scoop. (it is rounded where the bottom of the can meets the sides). You will now have a 15inch wide scoop to mount underneath the radiator.
Get 2 long bolts and 2 pieces of pvc to use as spacers to force a gap in the bottom of the shroud. The 2 bolts also hold on the homemade air scoop. This forces fresh air up to the airbox.
To isolate the airboxes from the engine compartment, I cut one of those silver windshield reflectors to fit in the airbox area and attached with velcro. I tie-wrapped some of the remaining reflector around the MAF to throttle body duct. Seems to help.
