im dying to try one i hear they are some of the best beers in the world i just want ot follow a recipe that will come close to the real thing
try to find a westmalle, rochefort, st. bernardus, etc... there is quite a bit of variation in 'trappist' beers.
i've been reading 'brew like a monk' for the last few days and you're right, the yeast makes these beers. i have a belgian strong ale i made about 4 weeks ago, i had a little left over when i racked to secondary, so i put a half gallon or so in one of my kegs... it doesn't taste nearly as young as i thought it might. of course, it will taste much better once i let the secondary sit for a few months, but if you brew it, i think it's a good idea to try one every few weeks to see how the beer matures... hell, you're gonna have 50 of them, sneaking a few won't hurt anybody.
i would recommend the practice of adding the candi sugar after 3-4 days of primary fermentation. i did this with the aforementioned belgian strong and it kept the fermentation going nicely... an interesting thing about the trappist breweries is they usually only do a primary fermentation of 4-5 days to get close to the target gravity and then some condition it further in another tank before refermenting in the bottle to really condition it... however, i don't think any of them, from what i have read so far, condition their beers for 6 months or anything like that ( i could very well be wrong about this ).
anyway, i say go for it, the belgians are a fun group.
