It feels like I have a lot of work ahead of me.
Yup.
Just a few ideas:
- Remove whorled/multiple branches until you have two you wish to work with. Develop from there,.
- If the knobs are too large or create reverse taper, I'd cut them back & start over with new shoots.
- If you want the straight trunk, select branches that allow it look proportional to a tall straight tree & remove the rest.
- For taper on the trunk you have, you can
A: allow sacrificial shoots to grow at the base & periodically prune back.
B: Attempt thread grafting (same idea as sacrificial shoots, but you get to choose where you want them).
- David Cortizas has some good videos about thread grafting for mame size bonsai:

- For a bigger trunk, put into a larger container & let it grow wild & crazy until you reach desired trunk size. Then cut back where you want the taper/curves to start. Repeat. (The main trunk areas won't thicken as much until the section/sections above it approach the same diameter. Example: If you cut back a 1" trunk to a 1/4" branch, the 1" trunk won't increase much until that branch catches up in size. This applies to primary & secondary branches as well).
- If the top section has more interest with branches & taper, you may try an air layer.
