New 1st gen owner from Los Angeles! Recommended service and maintenance?

So my 2nd gen prerunner was wrecked while parked. Decided to pocket the extra funds and replace it with a great condition 1st gen 4 cyl 5 speed 5 lugger.

I'm looking up service intervals and most stop around 100,000 miles.
Any advice for what I should address next?
I've included some photos and a screen shot at the end of the spreadsheet with all the maintenance for the past 100,000 miles.

The truck is nearing 200,000 miles and I want this to last another 200,000 miles
The truck has no issues other than feeling a little sloppy handling-wise to a more modern compact car.
There's a tiny screech on start-up too that should probably be addressed.
At idle it shakes a tiny bit more than my 2005 tacoma did. Maybe motor mounts? They've never been changed though visually they don't look all that bad. just a bit dirty and ashy.

The truck is on the original clutch. Maybe this should be addressed first?
But I want to really ensure the motor and all is serviced and I don't miss something that should be done.

I've attached photos of the truck and a spreadsheet with previous maintenance.

Thanks guys!
