The raid browser is currently bugged from what I've noticed. You are able to browse raids, but you are unable to list yourself as eligible for particular raids. I do not know if this is caused by a flaw in the system where it "thinks" you are undergeared or not. I still have this issue myself despite average item level being higher than heroics which leads me to believe the system is broken. If you consider when it says you are "ready" to start heroics at about 4 item levels below all gear pieces being maxed for the tier prior (333, or normal dungeon difficulty) then you would expect the first tier to follow a similar suit and say you are ready at very close to 346 or heroic gear, probably around the 342 item level. I'm at around 350 item level and still have this issue you describe which leads me to believe the system is broken. You can browse people looking for raid, but are unable to list yourself for as looking for a raid (which naturally means when you browse you won't find anyone either).

You should be very close to the item level of the prior tier, in this case heroics which are 346 before heading into the next teir of raiding which is 359. I mentioned the number 342 as a generic number based on how high you had to be in order to queue for heroics.
Raids however don't really have a set requirement. As such if you are actually able to put forth the necessary DPS, Tanking, or Healing in your current gear, then you are ready. For each individual it will be different. For you personally I think you should probably spend a little more time in heroics and try and get over 340 item level, but if you think you're ready and can get a strong group by all means.
Baradin Hold is on the Southern Island of Tol Barad in the center of the zone, the enterance is on the west wall (looks like a cellar enterance). That is the actual PvP zone fought over every two hours, not the questing only Northern Island. If your faction controls the zone this is by far the easiest raid encounter to start with.
