ST205 - Replacing all 4 rotors & front caliper rebuild, DIY - I did it. Options

[Jeebus]

Hey folks,

So when I last took my GT-Four to get my new wheels (to a performance garage), the mechanic told me one of my front calipers was seized, and my rotors were not in the best condition (pads looked new though).

I've gone ahead and bought replacement rotors and received my caliper rebuild set in the mail today, but I'm not quite sure whether this is a task I should do on my own with my limited mechanical experience, especially working on something critical like the brakes.

I've phoned the garage, and they've quoted me 4~5hrs of labour.

I've also looked around the web to see some FAQs and have found these two DIYs:
GT4dc.co.uk
GT4OC.net

Now the question comes to this, should I save myself $350 in cash and attempt this on my own, or get it professionally done?

The part I'm most unsure about (since I've never done it before) is working with the brake-line (bleeding and such).
What will be the most difficult & critical part if I decide to do this task myself in my own garage?

I should of known that the gt4 would have some performance calipers. but so then does it use pistons pushing from both sides? I guess I have seen the racing style ones with 4 pistons.
also, do we have a thread on how-to rebuild calipers? even regular ones?

and you would want to use something like a bearing grease for the slider pins anyway, the silicone spray breaks down at a lower temp and could lock up
if the brakes get really hot from hard use or dragging. but I guess you don't have to worry about that anyway

but that silicone spray stuff is great for things like door/hood/hatch hinges, door latches and anything else that gets squeaky
