My BD is BG, so that is as far as my guide can go, but I put out some experience from our main BD in our clan that is far into AG.
I take it you have experience in this game, have top gear at your disposal (buffbots we leave them be ok)
1-10
Stay around your DE town, hunt the yellow and light reds as much as you can, in Bronze with a dagger you should level like a flash.
10-14
Go do some Zombie killing in Swampland
15-20
Ruins of Agony is your place to be, fast spawn, good xp, good enough to get along, class change ain't hard to do
20-24
Take full advantage of VR4 and hunt in NoS till your VR runs out
25-40
Or you get that SE box out, or you get a clannie kind of enough to take another SE out and start poling in cata's or get some Brigandine-ELS/Mithril and start smashing around AC > Orc Barracks > PH > Hardins
40-52
Full Plate and Raid*Spirit or Raid*Raid is the way to go, depends if you like speed or focus. Enchanted Valley or Branded are quite nice, early 50's Apostate is a great place to lvl up. This is the best time to manor seeds and make money for BG
52-61
Blue Wolf with SLS*TSU or SLS*SLS (same story as CG) although some prefer Doom for extra HP and stun resist. Stay in Apostate first rooms till they turn blue after that do Forsaken Plains till 61 at the least
61+
Well havent gotten there but Majestic heavy and Kesh*Kesh or Dama*Kesh seem to be the better options. Id stayin FP till 64 at the least before moving to other places.
BD solo 61+ = Tallum and +4 Kesh*Kesh, for solo you want both those +8% atk spd's (or the new Interlude duals +4 work too)
some like to keep a nice OE'd set of TSU*SLS duals for the crits, but i prefer the atk spd
I only use my Majestic set for PVP, i would 1--% suggest Tallum, especially when you get it +6 you get a nice MP regen boost (more dances, magic while holding dances and such)
