Does an STA-747 have the range to cross the atlantic with some island
hopping ?

Yes. N905NA took Enterprise to the Paris Airshow in the early 80s. By
the way, the acronym is SCA (Shuttle Carrier Aircraft), not STA.

Say it lands in Morocco or Spain, what would the stopovers be ? I take
it they would choose military airfields in england. Would it have to end
up in a major commercial airport on its way to Florida ?

I don't know the exact route, but there are photos of OV-101/N905NA at
CFB Goose Bay on Wikipedia.
