Restoring A Vintage Hagstrom Bass

Hello all, I'm going to be restoring a vintage bass, and since I'm a total beginner in this field, I thought I'd share my journey here and humbly ask for some help. My goal is to bring the bass to a higher level of playability and beauty so I can maximize it's selling potential. Please refer tothe images above in reference to the points below.

The instrument is a red Hagstom Futurama II bass, circa 1964. It came to me through a friend of my Uncle, who apparently rubbed off the label and etched notes into the neck. Therefore, it seems that the bulk of the work will be focused on that portion. Here are the things that I think need to be done before sale. (Please feel free to add to this list if you think of something I do not, or to protest anything that seems like a bad idea!)

1. Clean the existing hardware. (I'm not sure how to do this or with what cleaner, etc. Much of the original hardware, tuning machines, etc, is slightly rusty and rather dusty. Would it be possible to spray paint a new coat of chrome on or can the original material be cleaned well? If so, how?)
2. Replace missing hardware. (There are several missing screws, and some rusty ones that need replacing, but luckily I have at least one of each missing item.)
3. Remove finish/marking from necks. (Removing the finish is a choice of playability, but removing the markings will prove to be more difficult. I suppose I should remove the finish first and then see how much further I should sand after that is done. I'm curious whether sanding off the markings would be a poor choice for any reason?)
4. Remove completely the marking on the headstock and revarnish. (I'm unsure whether this action would devalue the bass or whether the different would be negligible. For me, it seems like a choice of aesthetics.)
5. The bass may need to a fret job. (It could be a question of neck action, but several of the last frets don't produce notes that speak as well as in the low end. It seems some of the frets may be a little flat on the top, though it's hard to tell. I have tried to include pictures of this.)
6. There is a small hole in the bottom of the bass (which can be seen in the last picture), right near the strap peg. I'm not sure what this is or what to do about it. Thoughts?

Thanks for reading this and for your responses. If you have any additional information to share about this bass, or any advice for my project, please feel free to share. I'm excited to learn a few things about bass repair in the process!
