Couple of things.
before a toon goes out to RvR he needs lv50, basic template, cl10 or have the bar moving to the right (that's an extra 200 hp), ml 4-10 class and role depending and as close to rr3 as possible (IE Battlegrounds).
From the battleground you learn how to play your toon, what your role in a group is and what toons are wanted at 50.
You should be able to get a guild there which will help with template ie crafters
Minimum RA = LW1, minumum gear = endo pot, water pot, tin foil hat, horse and saddel bag with 2 pieces of siege (ok the last is my deal)
This is a group game not a solo one, solo if you like but thats up to you.
You can not spec 50 cave on your shaman (or staff in the friar example) and expect a group to run you, get over it.
As to the template, you don't need end game gear to compete, Dragon slayer, Dragon weapon, champ weapon, Player crafted, basic artifacts, even Epic dungeon gear (TG Sidi) are affordable and readily available.
You get ML10, Levi, seasonal quest items, rare x10 loot drops etc as you play, join raids, or buy from other players (you do gain gold from killing elfs you know).
At RR5 you work on a template to replace your starter temp, by that time you should of figured out whats is important and have access to a few or all of the leet gear you think you have a right to right out of the gate.
Play what ever class is fun for you, yes even a thane can add to a group if played right, play it wrong and expect to get called out on it "mezz braking lag hammers of doom".
