well...i've played 8 characters through lone lands and never had a single problem; the way i do it:
21- go to lone lands (forsaken inn)
leave forsaken inn with the 'my deputy' quest at around lvl 24
24-25/26- the camp near the goblin thingy (where the 'my deputy' quest leads you)- these are lvl 24/25 quests btw
25/26-27- the dwarf midway from the inn to ost gruth + the mine next to him
27-29- ost gruth
if you're missing any quests go do the lvl 20's epics and you shouldn't really have any problems.
