1. Do TB. you're horde on a PvP server with a 25:1 horde/ally ratio (according to wowprogress) The trinket is 125 commendations (plus maybe a little dungeon rep if you don't have it yet). that's 13 days. If you're going to worry about .25 CTC coverage, just bite the bullet
2. Personally, I've very much in the ignore cheap VP items until you have the key ones. The reason being the cheap ones have less total rating on it, plus the 4pc is typically the goal. However, that being said, in your case, I'd suggest trying to get the 4pc T11 (or at least the helm or shoulders drop) so you can go 2pc t11 and 2pc t12 for Alyzrazor. I'd suggest probably the gloves + legs for t12 with the chest + helm/shoulders from t11. Then, look at itemization and item level.
Right now the 378 ring over the 346 you have is a bigger gain than the 378 neck over the 365 you have.
Now - as to the original question - CTC or balanced dodge/parry - CTC is the way to go. It won't make much difference overall, but higher CTC means smoother rage. Dodge/parry balancing (with parry slightly ahead) is nice, but if it's out of whack and you still have better CTC coverage, it's not a big deal. Think about it... I want to be less protected just to balance two stats that are supposed to be protecting me?
Other point - ANY points in Cruetly without capping DW is less than optimal. DW isn't just a TPS increase over cruetly, it's a DPS as well.
