A) You come out to a LS that does these things on RPC and say "Hey guys I'd like to do said content. You mentioned wanting to try to run these to help out. I'd love your help."
B) You returned at a time where it doesn't take you long -at all- to get your item level up. Or get gear. While the new dungeons may be an issue, you still have the i70-i80 gear dropping stuff. You could start doing hunts. Check PF. Join. If the ilvl is too low, go into the lower level dungeons. Ask LS from A) to see if people will run dungeons with you so you can try to get the loot or get the tomes. Soldiery is unlimited! Get that wonderful tank gear on your PLD and use it for your Warrior when it's 50!
C) Enter dungeon say "Hey guys, just returned to the game and I'm rusty and new. I'll be doing my best. Any help or advice is appreciated."
D) Gear between PLD and WAR is shared. If you want to just level WAR then this content isn't stuff you should have problems with until later.
If you haven't started the content, you've still got lots of time because you still need the quests to unlock the content and you do need the gear so take your time learning these things. I would not recommend not watching a video for t5 (or t4) but all the other BCOB stuff is easy to talk about. See my comments about tanking BCOB.
