I am wanting to complete The Fremenic Isles, but my agility is only 38. Is it possible to do it with an agility pot? If not, whats the best way to get two agility levels?

Im pretty sure you can pot, but to be honest, you might aswell get 40 agility. Just do a few laps of the barb course and you're set.

Alright, i started the quest and im at the part where i have to split the logs. I definitely can't find where to split them.

There's a tree stump on the first island just to the north.
