Automatically replace shock boots (and other nearby parts) withshocks?

If I am getting my shocks replaced at ~40K miles, I should probably
replace the boots at the same time, yes?

One thing that puzzles me is, good-win-racing.com wants 29.95 for each
"factor shock boot" (this is for an '03, so no bump stops attached to
them), and they seem to have decent pricing with some other items I
have looked at.

But miatazone sells an "OE" boot for only 11.77.

That's a huge difference unless I'm missing something!

Also wondering, while I'm at it, if it's necessary to replace those
other parts nearby, such as the bushings and mounts. Do bumpstops
wear out? If I were faced with replacing those I would lean toward
options that are stock-legal in autocross (if anything other than OEM
qualifies), though I suppose that isn't an absolute if there's a huge
gain to be had.

As always, thoughts and advice are appreciated.
