Welcome Lauren...
I was looking through elixant.com and noticed all their sites are hosted with Cpanel, this is a good thing. Surpass can transfer your Cpanel account from elixant to Surpass's Servers.
As far as what plan you should choose: I was unable to get into your forum and see how busy your forum is. Regardless, I would contact the Help Desk (24 hours... you don't need a username and password just an email account) and let them know exactly what you need/ are looking for. You can submit a ticket at
http://desk.surpasshosting.com
You could also provide them a link to this thread if you don't want to reiterate everything.
Good Luck
