At any rate, if you're staying F2P train your Woodcutting skill. Cut yews, then sell them for a 100% profit via GE. I'd suggest buying the bones for 43 prayer (probably would take around 1k yews to accomplish this), then you'd be all set for your F2P combat career.
If you're not a huge fan of skilling like that, just go and train combat. That's nearly all I did while I was F2P, especially when I decided to become a member. Moss Giants were the monster of choice for me, though there are far better places now.
