Probably not, unless you've changed something in the valvetrain.
The shims wear very little, even engines with 200K+ don't tend to be out of adjustment.
Adjustment is usually required when you change something with the valves, like valve seats, or a new cam, ect.

Basically, you use an allen key to compress the valve, and then a flat head screw driver flipped on its side to hold it compressed by the edge of the bucket. Once you have everything in place, use a mini screw driver and a magnetic pickup tool to fish the shim out.
This is basically how I did it years ago before I worked for Toyota. Not that hard, but it takes a little bit to get used to it.
Definitely a one man job.
