If you have some decent melee weapons you may find the kill rate goes quicker if you use a merc to heal you on the animals in FoS. And the rate of xp might be a little better, even though you have a 2nd toon in group. You'll want to see how it goes for you.
Depending on your amount of aa's (for defense aa's) and your current gear (for ac) you should probably hold off on the named animals. I would recommend around 4k buffed ac, with some ranger tricks thrown in, if you want to survive one of them. Ranger tricks being stuff like outrider's evasion, weapon shield, guardian of the forest, etc. Again that depends on which aa's you have. There seems to be lots of people looking for those nameds though, and with even a semi-decent group you could tank them easily enough.
Honestly though, since you're a ranger, you should look on
EQOutrider in the headshot threads to get an idea of how to better maximize your xp at these levels.
That could be a better way for you to get those aa's done, if you still need them, and then come back to get the augs/gear off the nameds in FoS.
