Hey... Time to get a few tools... Sounds like fun Fun FUN!
Possibly the only thing you need the bike shop for is to tune the wheels if you are not familiar with it. You can get a Spoke Wrench and a Tension Meter for less than 25 USD and true the wheels yourself. Youtubes abound... Don't be afraid. You are not going to hurt that Motobecane. Especially if you send pictures our way when ya get stuck...
Like I said... fun, Fun, FUN!
This is my favorite Bar Wrap: BV EVA Road Bike Handlebar Bar Tape
Even though they are a little harder to mount I use modern day Brake Pads just cause they work better: GPMTER 2 Pairs Bike Brakes Pads Set, 70mm for Cruiser MTB Mountain Bicycle Universal V-Brake Blocks with Hex Nut and Shims, No Noise No Skid
