I'm sure your LBS will deal with most, if not all of your issues. Most likely, your bike needs a tune-up, which most shops offer free for new bikes after the break-in period. If you ask them about the saddle, they'll probably swap it out, and I bet they'll give you whatever color tape you want to make you happy. Oh, and they'll true your wheels too. I know I'd do all of the above, no problem.
