Yes, everyone has slightly differing methods. There is plenty of info in the "sticky" threads above, including reviews of bms, heat guns, and a guide to corretto roasting with lots of pics.
All your questions have been asked plenty of times. Best bet is to do some more reading and just give it a go. most of us are using what was conveniently on hand at the time.
(Eg. I roast, remove and dump on caesar stone bench to cool and bag within a few minutes. the bench works well as its large and nearby, but others use buckets, colanders and fans etc.)
