Some people jump straight in, others take their time. Do some reading and see if you have a good understanding of process - there's a lot of info here including a great article towards the end of the wiki articles by Jase. Read palmer, ask questions here if you can't find the answers elsewhere etc.
If you want to, then have a crack. You can always take a step backwards if you realise it's too much but it's more work than anything else: it's not particularly complicated (unless you want to make it so), just time consuming and effort. Personally I enjoy the time and effort spent so to me it's worth it.
If it's what you're into then go for it.
I agree with Bribie in the sense that you do need a good understanding of how fermentation works and I chose to go about it the long way, step by step. However I'd never want to discourage anyone from doing dsomething in a different manner to myself.

Chappo no 1 will show you a much better way though I've no doubt. You should be in good hands.
