The two entry bracelets are found, one in the Beneri labs (in the destroyed area with the loose golem), and one in the Beneri vats (dropped by one of the security golems, I believe).
In the MoT, itself...well, there a dude called...um...Tolleran, I think, who will shape you for boocoos huge amounts of money (5000 or 6000 a stat, I think), to boost several stats. Other than that, you just go through the place, advancing slowly and carefully so as to avoid drawing to large of a mob around you, and wipe out everything. Leave to heal when necessary.
In the MoT caves, I recommend taking a couple times just to run around in combat mode, not fighting but just looking around and getting a sense of what monsters are where. Most importantly, find the machine that spawns new creations (go west, then north, along the east side of the pools of water, and you should find it). When you are prepared to take on the caves for real, you'll want to have (from base stats and/or from items) 20 mechanics. Enter combat as soon as you get inside, pump yourself as much as possible, and race to the monster generating machine (rough NW of where you start). With 20 mechanics, you can deactivate it and stop it from spawning more monsters (and the monsters it makes don't give experience, so they're pretty useless except to annoy you).
Then, at your leisure, work your way through the place slaughtering everything, again being careful to advance slowly, try to take on one enemy or cluster of enemies at a time. Once you've wiped out everything else, in the far NW corner of the caves you'll find the super boss creator monster thingy. Whack it lots of times and you get a boocoos good Omni Charm. And of course there's other really nifty loot throughout the cave.
That's all I can think of.
