After a few track days there is some obvious wear on the inner of my front tyres.
This might just be from hard use but it seems like camber wear to me from negative camber.
The wear on the second block on each side appears definitely to be from hard use.

Does this adjustment bolt adjust camber? This is the bolt of the lower suspension arm.
That is two notches off centre so if it adjusts camber I would consider going back a notch to save the tyres.

I don't really understand the manual. It makes it sound like camber and caster are adjusted with this same nut. If I go back one notch what will happen, and will my toe be screwed?

Do you know how to align suspension? Because of you don't I wouldn't even bother. If you think your alignment is off, take it to a shop.

they are, along with toe.

the lower arm is an A arm (its a weird A...), and there is an adjustment at each leg of the A. the ball joint is at the top of the A. so to adjust camber, you adjust both. adjusting only one changes caster as well. and since you're changing the length of the arm to change alignment angles, you're also changing toe, so if its wearing on the inside, drive harder or go to a shop.

 

In my experience inner tire wear is only accelerated when you have a combination of camber and toe misalignment. For instance I run 4" negative camber on the front of my car and it wears very even. The only time it chews tires is when the toe is out. So I'd get to alignment shop as others have said.
