There is no standard for the spacing of components, nor should there be. We have a difficult time picturing your 0805 at a 45* to the wave and the safe pin, but we'd guess this spacing needs to be 10 thou.

Right you are. Count on it taking at least an hour if you've never done it before. I think they made the pro-head way too complicated. Standard UP style heads are so much easier.

It realy depends on your product. Tighter tollerance boards require a better machine, which costs more money. Multi-layered baords wih a alot of heat sink will require preheat - something a lot of selective solder machine do not come standard with.
