Well, obviously something is dragging. Can be the brake, can be the freewheel, can be the axle bearings, can be tire rubbing on chain/seatstays. Impossible to tell from your question. Take the wheel out of the frame, twirl the axle with your fingers. Don't expect it to keep spinning, but it should move easily. If it doesn't it's time to clean, regrease and adjust the bearings. www.bicycletutor.com, www.sheldonbrown and www.parktool.com can tell you how.

It would depend on a few things. Probably most important is comfort, whats right for one person is all wrong for another. Also depends on what type of bike and what type of riding your doing. I like having my weight quite far back over the rear wheel as its good for jumps and dh but on my road bike I have my weight alot more forward.
