+1 on visiting HammockfForums.net. They have a ton of great info.
Generally, though, if you're looking for ultimate comfort, I'd recommend either the Dream Hammocks Dangerbird (the 11-foot-version):
or the Warbonnet RidgeRunner:
Both are INCREDIBLY comfortable and have built-in bug protection. The styles are a bit different - the Dream Hammock is a gathered end (more traditional) and the RidgeRunner is a bridge hammock. Generally speaking, most find the RidgeRunner to be a bit more comfortable, but may not choose it due to the weight penalty of the poles. Again, if using it at home/car camping, though, it's not an issue. You really can't go wrong with either choice.
As far as tarps, if weight isn't a concern, it's tough to beat a Warbonnet Superfly. Tons of coverage, closable doors and a decent price:
