The only dumb questions is the one that is not asked. Check out Goldmoney.com. I haven't invested yet, but it just merged with Peter Schiff's gold company and I think it looks promising.

Most importantly, do your research, understand gold very well, and then do whatever you're comfortable with and can afford to hold long term.
