Thanks, Donna! Especially for the definitions of the two types of redirection. Couple of questions...
If I went with the stealth option would it be possible for customers to bookmark product pages even if they can't see the true URL?
Also, can I redirect only a subdomain and not the main domain itself?
Okay, I'm off to GoDaddy to read up on it. Sometimes that stuff makes my head spin a little so I wanted to get some person-to-person feedback first!
