Hey Dattoact,
I envy your setup. I have what is little more than a carport with a dirt floor for my Rally 1600 rebuild. Shelving is a must with full rebuilds and I can see you already have some. Make sure everything you take off the car is marked, I tried but still had bits and pieces go missing.
It helps if you have a plan with what order you do things in. I didn't, and subsequently fell into the trap of doing 5 minutes work on the easy stuff, and never really acheived anything of significance after a whole weekends work.
Doing it yourself is better in my opinion as you learn exactly what has gone into everything on your car, as well as the condition of every part and (usually) how it works
