What skills do I need to get enough overgrid for this?

New Citizens shouldn’t fly and lose Gilas. Do you like a Caracal fit?
Or you ask here: PvE Ships & Modules - EVE Online Forums

I could open Pyfa and try to answer this question for you, but if you still have to ask that question I recommend against flying a ship that expensive.

I’d suggest training reading to III, then look for skills that give you powergrid or reduce fitting costs.
