tuning newbie
If you want to play it safe, stick with www.efilive.com or www.hptuners.com. Both companies are on the leading edge of tuning the LS series motors. You can download a demo version of EFILive from their site.
Learning to tune is a worth while investment. Would you rather pay $600 once so you can tune yourself, or pay someone else $400 for a tune every time you change your mods?
As far as the dyno goes, a dyno is a very useful tool when tuning. "Home tuning" allows you to dial in your idle, part throttle, and various other things with out the cost of the dyno time. You will still want to use the dyno to tune WOT.

I think the competition between EFILive and HPT is great. The way they keep "one-uping" each other means a better product for us.
