Get your runecrafting up!
It is the most money in f2p by far!
Combat-wise I'd suggest getting 78 def and just training str at spideres (vest/stat pure) and maybe go for 99 wc if your really bored cause your fairly close.
I would also agree that rune craft is the best f2p skill by far. Stocking up on tokens in Great Orb Project and selling them when you get members is very profitable.
