Cheap service parts in West London ish area

[FG1]

Anybody know any decent places to service parts for a K6 SV.
I am probably looking for:
Oil
Oil filter
Spark plugs
Air filter
Front brake pads

I am going to attempt a service and brake pad replacement for the first time so if anybody wants to walk me through it feel free to shout out.
I feel like it should be relitavely problem free, the brakes are my only concern. Is it just a case unbolting the calipers, remove retaining pins, push pistons back in, fit new pads, bolt everything back on ???

a brake pad change is fairly easy and will take very little skill 2 do the job so dont worry about it if you get stuck on any thing or for get where 2 put something just pop round the other side of the bike and take the other caliper apart and you will see where all the bits go again lol.

M and P so a 'service kit' that comes with oil, oil filter and 2 spark plugs. I also had a quick turn round on the order.
