Only use magic and range for training slayer or you'll regret it. Doing slayer with melee is painful.
The only quests I ever did was the ones to get me mith gloves, climbing boots, zammy book, and the one to get the spec for the bone dagger.
I prefer 1 attack.
You wear what you can. Iron armor, d hide, str/glory/fury, red? machette, slayer staff, obby maul, etc.
