Halp!

Woodcutting hotspots--Ivy.
Everyone's doing it to 99 nowadays and you have the level to start it off. You can find it on city walls and start chopping away. But first, you'll need a hatchet. You can get a hatchet or pickaxe from the Grand Exchange, knowing how people will be buying and selling it many times there. You should start off with a rune hatchet too. And my favorite part to chop Ivy was on w132 at the South Falador Wall, easiest to get there with a Cabbage Port ring and running North. Note that to get the ring, you'll need to do the Lumbridge/Draynor achievement diary, and keeping that ring is an essential.

I guess it could also help you to explore Lumbridge. It has been updated so many times that now it has found so much use. There's a fishing shop there for your lobster pot. There's also a question mark on the upper left of your screen, it opens up the advisor, so whatever you may be doing, it gives you somewhat fair advice. (For the non-members things you may be doing, but he can help you get started on the new things and provide you with free samples and directions to shops/services, etc.)

Sorry for the organization on this post, but I boldfaced the things that were important.

Hitpoints was changed to Constitution and everybody is raging about it
Shattered Heart D&D gives you free minor xp in skills as you collect the stones. Complete statue in your POH takes 30 weeks and does nothing, everybody is raging about it
Some old weapon graphics were updated if you hadn't noticed, and everybody was raging about it
Bonus xp weekend was introduced, there is a chance that it will happen again. Everybody raged about it
Merchanting clans manipulate the GE, everybody is raging about it
Most combat items almost doubled in price. Poor people raged about it

Go kill green dragons. People rage when they can't get kills

The best thing to know is that the Grand Exchange makes it easier to acquire almost any item. The prices may vary, but you can get whatever you need from the Grand Exchange now. There are not 300 qps, quite a few more skills, and changes to old ones. Like some people said already, start by making some money and you should be able to do whatever you want once you have a little bit of money going.

It would be helpful to build up some capital first. Try your resource skills (i.e. mining, woodcutting, runecrafting) to build some wealth so you can buy some equipment.

You could sell that dragon scimitar and whip you own and use that money to buy other things that could make more money. Buying some herb seeds and farm those will bring you a decent profit, then you could get 70 range and use black dragon hide armour. You should then make pretty good profit at the dragons as well as the herb profits coming in every hour.

kill green dragons to build up your bank, then proceed to spend money on increasing your levels.
