No problem! You should have only 2 wires attached to the starter itself. 1 big one, and 1 small one. Be careful with that big one, thus the reason your battery needs to be disconnected.
Once those 2 wires(and battery are disconnected) you can use a 15mm(someone correct size) socket and an extension to remove the 2 bolts securing the starter. Careful with the last bolt, the starter is heavy and WILL come down like a bad hangover.
Installation is just in reverse. Careful not to tighten the wire nuts too much, you may end up rotating the whole stud and possibly breaking the plastic.
