Brakes/Rotors....have to do front and rear at the same time or no?

My fronts are getting pretty bad, the rears I don't really notice. Is it alright to swap out the front rotors and brake pads now and save the rears for spring time or is that a mistake? Which take the brunt of the stopping force?

The front does most of the work (70-80%). I'd fix the fronts now and if you wind up needing rear brakes later, change them. Until that time, I'd swap the fronts and run the rears as they currently are. There is no danger from doing that and it's quite common to do so.

I agree. While I generally will replace both left and right at the same time there is no reason to do both front and back unless they both need it. Replace the fronts, and get the backs when they need it. You'll be fine.

Nope, not a problem at all. The LS1 has the brake bias shifted pretty heavily to the rear. A slightly more aggressive pad in the front is often useful to increase performance and prevent what we refer to as "brake hop". Brake hop is like wheel hop, but during very hard braking. The back axle begins to bounce violently. So, a slightly better pad up front isn't a bad thing and I think you'll be pleased with the results. If you add HPS pads to the rear, that will work fine for street use as well (and many people autocross on just such a setup). For extreme use (road courses, etc), I'd run a more aggressive pad in the front an a stock or HPS pad in the rear, but we're getting far ahead of ourselves at this point.
Basically, yes, you'll be just fine with that setup. You'll probably be very impressed with the results.

just autoX for first time on my new brake pads. Put the Hawk HPS up front and left the original in the back. Worked like a charm. Honestly, the difference was absolutely crazy. My first run I was braking waaaaay early bc i was used to the crappy worn pads

And if he stops 12 feet shorter and avoids rear ending someone for the cost of a $60 set of brake pads, what's that worth? Parts store pads are great for parts store cars (that don't make 300+ hp and weigh 3,500 lbs). A pad upgrade is money well spent in the opinion of many. Do you have to? Nope. If it saves you being in an accident, is it worth a few extra dollars? It is to me. Only you can decide for yourself though.
Be safe.

While even certain "streetable" pads can be a little on the aggressive side (can prematurely wear rotors down to minimal operation thickness), with a little bit of driving style change, they and good rotors can last long and if they can provide a decreased stopping distance when called upon, it's a win win game.
