Glad to hear you had fun! I had a blast as well, thanks to both you and Brain for coming down.
I remember both of you did have some questions about the starters, and I don't think I described them very well. They generally come with 3 of your basic line troops (you'll use these in most games you'll play), a straightforward heavy infantry, and 2 more specialized infantry (Camo, Infiltrating, Drop Troops).
All of the models in the starter sets are useful. There aren't any truly unplayable units in the game, nor are there any "must take" units. Instead each just presents a different tool for your list, depending on what you want to take.
For me, I can do some Saturdays (not all, and definitely not the next few), maybe a Monday here or there. Tuesdays are pretty good too.
As far as next time, I could do this upcoming Monday or Tuesday (10/27, 10/28).
