The paranoia is wholly justified and appropriate. IT is not metagaming inspired.
Friends + Good Game = FUN That is the point. Remember?
First, the Paranoia is not metagaming inspired, but it can grate on the player as well as the character. I don't know exactly how long this has been going on, but if every session is like this, it can realy get on a players never. It realy does depend on the individual players.
Good game and fun is in question here. If you as a player feel that the game is getting advisarial (And I see signs that it could be, but I will not rush to judgement), then perhps you should sit down with the GM and find out what's going on. If you're having fun, tell him that, but make sure he knows where your limits are. If you're not, tell him why.
It's one thing to have a disagreement of the RAW, and have the GM make a ruling you disagree with. You simply move on, and discuss it afterwards. Players that can't/won't drop it can become a distraction. But with new house rules, that's rough. And it's not a minor one, or one that works to the players favor either at the time either (Those are always nicer to find out about).
My feeling is that you're worried that if you tear appart his well planned encounters with better planning of your own, he'll get upset about it, and that leads me to believe you feel this is becoming an advisarial game. Otherwise you wouldn't be worried about undermining his fun by planning for his tactics. I hope that your tactics work well with the rest of your party too, so they feel included (The tenticle, entangle, fighter bash sounded like good battlefield control tactics to me).
