My plant came in a 4.5 x 5-inch pot. The braided trunk is about 8 inches and the whole plant is about 18-20 inches tall. When do I replant it and is there a certain kind of soil needed?
Repotting should be done every two years.
Choose a pot that is 1 or 2 sizes larger then the existing pot.
Repot during the summer months while the plant is actively growing.
Use a commercial potting mix that is formulated for cactus and succulents.

In reference to the cuttings of a money tree, do I plant it in dirt right away or root it in water first? I have a cutting from my tree.
While cuttings will readily root in water, they normally don't transplant as well as those that have been rooted in soil. Therefore, you may want to go ahead and start your rooting in soil right from the get-go for stronger root growth.

What is causing my pachira aquatica to ooze sap from the leaves? what can I do about it?
This is transpiration and may be due to overwatering.
Here are some articles with more information.
Firstly - I'm not even 100% sure it's a pachira aquatica... It seems to have a really, really dry trunk (especially at the base of the plant) but still happily growing new stems and leaves. I haven't seen any photos online of this plant growing like mine, should I have been guiding it's growth? Is it going to die because the the main stem is so dry? Should/can I propagate the healthy newer stems? Thanks in advance!
This is typical of aged trunks. It appears to be doing what it should. Here is an article that will help you to care for the tree:
