Being 9 levels lower than the target mob I do not think you can realistically juggle mobs. Your miss and resists rates won't allow for consistency. Both Disengage and FD can be resisted. Lets say you want to juggle some melee elite just a few levels above you. When you get higher level you could use a combination of distracting shot and FD. As far as your gear goes, I would really suggest picking up lw + skinning if you don't have much cash. The dark leather + agi gear is pretty good for that level until you can do VC.

Also, if you want to make some good cash, and like to grind, go to westfall. On the north coast a little west of the center of the map is a windmill and little house. Its Northwest of the jangerlode mine or whatever. There are about 10 defias human mobs there that have instant respawn once their numbers get a bit low (when there are like 3 left, and you kill 1, another 1 or 2 will pop up). Just make sure one of your hunters tags the mob with rank 1 serpent and have one of your alts just looting. If your pets are on aggresive, you should be able to get a serious amount of linen, greens, copper, and xp/hr there.

After you hit level 16 or so, you can go to the west coast, north of the light house. On the beach are a group of about 12 crabs with the same instant respawn. Keep an eye out for old murkeye =).
