Try to aquire as many Justice pointsas possible. Turn it into Honor and buy the 476 PVP gear (it works for PVE) that should allow you to get into the earlier LFRs, keep plugging away at that until you unlock heroic Scenarios and ToT LFR and then farm those.
Thanks guys. I have gotten some pretty good upgrades, but I can't queue for random regulars or get into random heroics because of my ilvl. Right now I'm sitting at 421 and am currently friendly with the shado pan. I do however have just over 2k justice points saved up. Let me know what you guys think. Also any advise on rotations? Thanks again for your help.
If you need gear for heroics, blacksmiths make cheap 458 pvp gear than can definitely work for tanking as well. The socket bonus is usually pvp power, so gem what stats you need in there and you should hit 450+ without a problem. If hou have the gold/blacksmithing friend, get yourself a 502 crafted. That should be your biggest gear boosts outside instances.
The difference with being a tank is that you will get very fast queues on doing dungeons, and also that doing a whole bunch of dungeons might well be a good way to learn how to play as a blood DK. So maybe plan to do a few more heroic dungeons, at least 1 per day.
