22R-E is 8 M8 bolts (4 for valve cover, 3 for vacuum/electrical bracket on valve cover, 1 for valve on back of valve cover), remove accelerator and cruise cable from mounts on top of valve cover and push to firewall, remove spark plugs from mounts on valve cover, disconnect one side of front PCV hose, disconnect two vacuum hoses that go to power steering pump and take them off of mount on valve cover. Takes about 2 minutes. But an FJ60 - yeah that's a royal pain.

Adjust them hot. The book is pretty clear about this. I was experimenting with doing them cold and it's true that things change hot fairly minimally, but it's not consistent across all the valves. Some showed minimal change in clearance and some quite a bit. Adjusting them cold left me with uneven valve lash, so I went back to doing them after driving home from work. If 14 miles of highway and some stop-n-go isn't enough, nothing will be. My feeling is hot means operating conditions, not just the t-stat open.
Takes about 2 minutes.
As far as the junk, like Subzali says, just a couple of minutes. You can do about half of it with the engine idling (bolts for the VSV plate, spark plug brackets, plastic vacuum hose hold-downs, etc.) and leave the 4 valve cover bolts and disconnecting the hoses to remove the cover. Then from shut-down to exposed valves it's no more than 90 seconds, depending on your burned forearms tolerance.

I do mine cold like the rest of the world and every tappet on every machine I own and have had no issues. There is a service range of acceptable clearances. Probably far more important to make sure the adjusting screws have no wear at the tappet; these are cheap from the dealer. Replace them.

Hot is a pain in the butt. No thankee.

maybe mini truckers do em cold but certainly not the rest of the world. I can certainly tell the difference between a hot and cold adjustment on the tappets. The old days most mechanics at a garage would do em while the engine is running. I've seen it done on my 2f. Since I don't do it everyday if I do em while running it peens my feelers.
