The hops not in the beer is fine- I strain my beer before putting it in the primary fermenter. The hops have already given you what they were supposed to, so having them in primary is not necessary. No harm, either, though!
As far as the watery taste, I think that will improve alot in the next couple of weeks. Carbonation and conditioning do great things for beer- and you can't really judge the final product based on the taste coming out of the primary fermenter.
