So this laquer stuff. Did i understand correctly that it works as both a protective layer and soldering flux so i could spray it over the whole board and solder ontop of it? (something like that anyway)

Whats an SMD? Probably not because i dont know what they are.

How do you "tin" a board and what is scotch tape?

I have 2 soldering irons. the old one is the best although the tip is about a sharp as a balloon and the new one (brand new!) doesnt appear to heat up enough to melt the solder properly so i dont use that so often. I dont know if my solder is lead free (ill have to check when i get home)

Just having a look on SparkFun.com now to see if i can find that article

Edit: If any of these questions have already been answered then i didnt understand it
