I think a 6-weight for bluegill is a little overkill, but then again what the heck do I know?

A 6 is a good all-round rod.

I use a 3 or 4 weight and have lots of fun. You'll figure out what works best for you.

The best advice is to settle on a rod, then get out and catch fish.

I fish popping bugs or other surface flies until they quit hitting. I'll then go subsurface.
