Welcome to the forum dude. Its quite easy swapping the pickups as long as you are methodical and take your time. Its just a case of re-soldering the new pickups where the old ones went.
You just need a decent Soldering Iron with a nice tip and some solder (from Maplin UK or Radio Shack US etc).
Remove scratchplate and control plates.
Keep note of what you remove with a diagram and replace likewise, make sure your Iron is hot (let it warm for 5 mins) and 'tin' the new pickup wires (coat the end with solder before connecting up).
The neck pickup is soldered to the top horn control plate and the bridge pickup to the 3-switch lower control plate. Your finished soldering should look shiney and rounded. May be worth practising first on some spare wire, heat both parts with Iron tip before soldering (wire and point).
The seymour duncan website has excellent diagrams as well 😉
