To get credits in Halo: Reach with a silver, or offline account, you need to play offline Campaign, Forge mode, or local Custom Games.
You don't. Money in Halo 3 Forge is set to the map limit.
Yes, you can play up to four players at a time on one console in Forge, Matchmaking, Theater, and Custom Games. For Campaign, 2 players only offline, 4 online. Although on some levels you can get 3 players offline as well.

Yes, there will be Forge mode in Halo 3: ODST... but on the other hand there is two discs so there might not be in the halo ODST disc.:)
