1st come back at level 5... no really, its doable but you are better off waiting
the swamp has lots of things going on;
1 portal to the underdark
2 shadow druid tree [protected by nat-spirts]
3 the "sheep"
4 a monster hunter encounter
5 the hag house
if you have your little heart set on killing the hag i'd start by getting rid of her sheep 1st, then i'd make sure i can cast magic missile and i'd also want very good perception
as for guides without knowing your party and class thats just pointless
