Hammocks are a matter of prefrence really, there are different types and even with different manufacturers of the same type you may prefer one over another. The best advice is to try other people's out and see how you get on with them.
As for tarps, there are different styles and materials, all have their pros and cons, for example lots of people like the DD tarps however I find my 3x4m one heavy and far too big, I much prefer the silnylon cat cut tarp that I made.
Warbonnet kit is very good and though I don't own one myself my friend's blackbird is very nice and I'm thinking of getting a ridgerunner, I've heard great things about the Warbonnet tarps too.
