I'm not a DIYer, but I would think you should focus on fishing/cooking first to get food for training. If you're P2P, you should also get some herblore levels too. Train up a bit, only killing things that drops Charms and Clues. Do every clue, pages are nice since you get those neat books. The other rewards are snazzy too, though unless you get 3rd Age it's basically nothing but Rune and Black D'hide armor to you (and that's only if it's lvl3!). Do as many quests as possible, get a good amount of cash (from alcing, I would assume) and use MTK whenever possible. Barrows gives you high-end armor and a [cabbage]load of runes. Slayer is one of the most important skills, it gives you a large variety of resources from the diverse monster drops and gives you the ability to gain some more, high-end items (D Boots and Whips). You can also net a Visage if you're lucky, and the clues and charms will roll in.
