People have such different levels of comfort and ability with mechanics that it's hard to say how this will be for you. My mechanical ability is fairly high, but I remember worrying about assembling my Rad Rover. I just followed the instructions, step by step. There was nothing more difficult than turning a wrench. I couldn't believe it when I realized I was done, it was so simple.
Is Velofix (I think that's the name of the portable bike shop) available in your area? For $200 (I think) they will take care of everything as well as tune things up to start you off. I would have felt cheated if I'd paid $200 for what needed doing, but that's not a bad price at all if you're the kind of person who doesn't know which end of a screwdriver to grab.
