Steps
Level Astrology up to Ameria and get Ameria to 80 mastery. That will give you access to 3 basic astrology bonuses and 2 unique bonuses. Use dust you got from leveling Astrology to get some Fishing bonuses.
Level Fishing. Fish until you get both the skill and mastery rings. You will probably hit Level 99 by the time it happens. Keep diamonds. Sell anything else. Now it shouldn't be an issue to spend a million for the woodcutting two-tree upgrade, any of the fishing rods, and so on.
Level Summoning. Make a bunch of Ents for your woodcutting. Try to always have Ents going. You will get more wood and, more importantly, level summoning.
Level Agility. Second obstacle has a Firemaking bonus, and a third one has a wood/fire bonus. Definitely get these as you get to Level 30 and Level 30 for the requirements.
At this point, you have an 8% skill ring, a 5% skill cape, and a bunch of other bonuses. Jump back to Astrology to roll on bonuses with what you're working on.
