 I have similar drivetrain set up as yours, but my LS2 is a rebuilt, and I used the following:
-Engine oil: Penzoil 5-30W (non synthetic).  Used Walmart cheap oil in the first 50 miles.
-Coolant: Prestone green premix 
-TR6060 - Walmart cheap dexron 3 first, as the trans is used.  Then changed out to Redline D4 after 200 miles.
