I took my mini velo into the LBS and had them do a thorough greasing (hubs, seatpost, headset, BB), adjust the brakes (triflow, but the brakes are needing a replacement and getting it soon) and other adjustments along with truing the wheels. It cost $85 and was well worth it. Ask for a quote. Turns out the guy at the shop also had a mini velo and cut me a deal.

I think you need to learn how to take the tires off/on along with the tubes. Putting on the rim tape is super easy. All you need is Velo Wide rim tape (get 2, since it's 1 per wheel), tire levers and a knife to cut it.
