I was thinking of switching my 1985 Torpado. I've been looking at a couple options, but had a couple questions before I started spending money all willy nilly.

Do I need to worry about spindle size at all? I'm really nervous to buy a set of pedals and find they aren't compatible with the crank arms.
Should I start with finding the pedals I like best, or finding a pair of shoes first? Then figure out the second to match the first? How have some of you done it?

I'm open to any advise or suggestions
