1) What is the best thing to camp at with full guthan to make the most money along with decent exp? Also, What is the best thing to camp at to get the most exp and what is best just for money.
2) Where is the best place to use full dharok besides monkeys at Ape Atoll for exp and for money.
3) Not barrows related, but what do you think is best thing to range with addy arrows for money?
Most money AND decent experience seldom go hand-in-hand with one another, except in the case of Necharyaels and Abyssal Demons. Those both require 80 or 85 slayer to even think about, and then some exemplary weaponry.
Non-slayer related, you'd be best suited to camp at Fire Giants. Their loot is fair as is their experience.
Dharoking is a bit more risky as you must always be vigilant of the Evil Chicken, but I've heard tales of Abyssal Demons being perfect to Dharok, along with anything else you can fully protect against (which excludes monsters with more than one type of attack).
Ranging with adamant arrows will never let you net any gain, but if you absolutely must, Black Dragons are the way to go. You'll get two or three piles of it, but you'll harvest the bones and hides which are so valuable to crafters.
Full dharok works pretty good in any monsters with high hp and low def, come to my mind bloodvelds and black demons. Best place to camp for xp, bloodvelds again. For money you can try dust devils (if lucky drag chain) and some alch drops or like Makoto said fire giants. To range fire giants or any kind of dragons.
