How should I insulate the pipes leading from our boiler to the steam radiators upstairs?

Last year we had all the asbestos removed from the basement of our house. Most of it was on the pipes that lead from our boiler to the steam radiators upstairs. I'm thinking I should replace the old insulation. [more downstairs]

The outgoing pipes are about 2 1/8" diameter and the return pipes are 1 1/4" diameter. The guys at Home Depot said I would need to use the more expensive fiberglass insulation because of the heat.
1. How thick should the insulation be? 1 inch thick? 2? more?
2. Should I use the kind where you wrap the stuff around and around and then wrap duct tape over that - or should I go with the preformed kind?
3. On the smaller return lines can I get away with the cheaper plastic foam insulation? Or should I use fiberglass for everything?
4. Home Depot doesn't carry the preformed stuff for the larger pipes. Where can I get that stuff if that's what I should get?
