Yes, you have to give one of the upgrades to each summoned Gamin. Which also means: No upgrades, no summons. For Banasuva you can take either the Commands of Earth, and he can shift around with the place from Sandeep (Bonus points for 3" melee, and no lure/push for the enemy), or the Command of fire. No cheating is bad, but with positive flips its managable, and immune to slow is awesome!

Kill it with fire. Simple as that. Don't know about Colette, but Ramos has enough options to shove a Howard or Joss towards a at least a bit exposed model, which it has to be, to threat your heavy hitters. And with a lot of spiders, the more turns you get, the more activation control you have, so he can't trick you with that pesky bury/unbury/fast/attack-combo. Other than that, play conservative but normal, and if your opponent does charge the student in one of your heavies, kill it on the crackback... to lose one of your big models is bad, but to take them their only option to really kill them is worth it, I suppose.
