Hi Mate, Welcome to the world of Carping!
I'd say the best thing to do is keep it simple.
With a 2.5lb TC rod you don't want to be using huge leads. something like a 2.5oz will be fine.
Rig wise, stick to something like a simple hair rig. Size 8 curve shank hook on a braid hooklink.
The best advice for a new angler is try and go out with someone you know who fishes. If that's not possible, find videos on Youtube and just digest everything you can!
