Welcome aboard! You'll really like the extra set of hands with your wife and step-son there to help. I'm flying solo and it's pretty tricky at times.

Oh, and about which tools you should buy...um, well, I'm into my project for almost 1.5 years and still learning how hard it is to say no. Figured I had a decent set to start, but discovered a number of tools that are so helpful. I see Edwardb provided a link above to assist with recommendations.
