I service my car myself, its not difficult at all. If you wanna do a big service the go for Oil Oil filter Fuel Filter and a set of plugs air filter if running standard. brake fluid change. When servicing your car top up the levels i.e screen wash, power steering etc, check lights, jack car up ....check tyres (pressures/treads) cv gaitors, bushes, check for play in wishbones steering rack, track rod ends ect, leaks. just have a general look over. With regards to braks and coolant. I would only change your pads + discs if almost worn out, no point buying some then finding out they are fine, same with rears. Do you know when you last had a coolant change, if ages ago or you have done a fair few miles since the last change then do it. Ive prob missed a couple of things but you get the general idea. hope this helps
