I'd go for it - I'm not that clued up on engines and I managed. I spent a fairly long time over it though, double checking everything on the way. Just take your time, and be prepared for the air to turn blue when you do the passenger side - definitely do the drivers side second. It's much more rewarding that way round.
I didn't move the scuttle - maybe the wires would move further if I had done? Still, I got the passenger side one in place on about the 6th attempt.
Don't buy all the gaskets in the How To - just the necessary ones. There's one set which will set you back 60 odd quid which you don't need.
Buy a can of carb cleaner from halfrauds to clear the breathers. I did the throttle body while I was in there too.
LABEL ALL THE LEADS!!! I did, badly, and then had a right carry on involving a very early rise the next day to take the plenum off again to rearrange most the leads to get the car to turn over again.
Go for it - and best of luck. I have to say that the only reason I did it myself was that I knew where to come to get help (and judging by the 'Top 10 Saddo Oofers' - it's a round the clock service
)
