Generally speaking any ICC geared tank will not be doing Naxx unless its the raid weekly for their 5 Frosts. So you wont have to worry about competing with them for a shot to tank Naxx. Depending how fast you progress up through the raids you may see that when you get to ToC. Once you have honed your skills and worked your way up I would suggest looking for a raiding guild (if raiding is what you want to do with your game time). That way you can avoid PuGs that want over geared tanks for no other reason than they want fast and easy loot.
