1) Don't have the rulebook here, but AFAIK each model still on the table gets to pick one skill. So yeah, that's up to three skill points for Threshold, but the base points
also increase by 3 points (so Threshold Base Points go from 5+2+2 to 6+3+3=12 points). So four more skills and one member has to go!
**Edit**
Just saw LidlessEye's comment. Okay, that's something we obviously is wrong. I'll edit my post. Cheers for the input

.
2) Hmmmm, Command reads as follows:
"When nominated, a model with Command may also nominate two additional friendly models within 10. Note that a model may only use this ability when starting the turn in the Normal state". (from the demopack). These rules don't imply the model with Command has to go first.
Me and my buddies don't pay real attention whether the Character goes first or not. Works well IMO.
