I too played the Sunday Million! It actually wasn't as bad as I thought. I thought that given the 36000 man player pool it would take a very long time and be a massive crap shoot. Obviously it was a crap shoot, but since the playing field was so soft there were a lot of good spots early on in the tourney to amass chips.
My stack was up to 400bb pretty early due to some poor postflop play by my opponents. For example this hand:



I think I played reasonably well for the most part, but was pretty card dead when I needed hands. I got lucky to quadrouple near the bubble with 88 on a short stack, but with the quickly rising blinds I saw myself being forced to ship in the money light w/t8s and got snapped off by KQ and didn't make my hand (actually I made a flush, but he one carded me on the river for an overflush).
I think my big stack game is pretty reasonable and so is my short stack, but I'm a little bit hesitant sometimes to make correct ships with less than 10bbs and that's something I need to work on (mainly from a disciplinary stand point). I ended up finishing 3700th just in the money and short of the second bubble for 289$.
I'm definetly gonna check out the tourney section in Mathematics of Poker that Isura suggested and watch some videos on MTTs. After that I should be set for my first larger live tournament. I also picked up a copy of Mike Caro's Book of Tells. Phil Hellmuth's book on tells actually had better reviews across the field, but I'm not a big Hellmuth fan .
I don't think tells are as huge in live poker as some may think, but you definetly need to atleast be aware of them and conciously watch yourself when your playing as not to give away free information.
