Welcome to the SB community and to the Blitz! You'll find that the guys around here are very, very helpful.
Tell us what you're issues are and I'm sure several guys will reply back and we can all discuss things.
I'd also take a look at this site if you haven't already:
http://www.wargamer.com/Hosted/SquadBattles/
There is a section for archived tactical articles that I found very, very useful when I first started playing the game.

Using the User Guide is also very helpful.
