ok, so how exactly do you use cloaking? The rule card for it wasn't much help.

Also what is a korigan turn? I thought the Tie Defender was supposed to have it, but all I had were regular maneuvers on my dial

You start cloaked, to decloak you declare before any ship has moved you then perform a barrel roll or forward movement using the 2 straight template and then remove the token.

When decloaking you may not overlap obstacles or ships.

To recloak you have two options take the advanced cloaking device this automatically gives the token after you attack, or you cloak as an action the next turn.

ok, got a quesiton on the different maneuvers. Do you announce when you are doing a talon roll, segnor turn, or korigan turn? Or are they on the dials somewhere?

Also what do you reccomend so that the bases of the ships don't slide around so easily? one thing we ran into was that if we had ships close by each other, when we went to move our ship, sometimes the slightest accidental bump would move the other ship a different angle or whatnot

They are on the dial, but not all ships have them. For example, T-70 X-wing:

Right side of the table - those red speed 3 turns are Talon rolls, speed 4 between them is Koiogan turn.

Those manuevers are red for vast majority of ships, although there are exceptions, like TIE Defender with a white K-turn.

I use the little rubber bumpers that you get to stop cupboard doors banging when they close
