Hi JilL
You seem to be a very responsible person by looking into it so well done you

, you wont belive the ammount of people who purchase on a whim.
As jo says Hibernation is not scary or complex, check out the hibernating section to give you more info. Plenty there
Marginated torts have near identical husbandry requirements to hermanns and are lovely torts, i think they are well suited as a first tort. Like hermanns and horsefields.
Dont waste money on buying tables, they are easy as pie to make, a large empty drawer is perfect, and obvious heating and lighting requirements too

save your money from buying from a shop, they sell at 400% profit. at least
Finally dont feel like they need company, they dont. and male and male can fight.
let us know if you need anything else
