Are these the original struts? If so and you do decide to do it, I'd just mention again that you should just add new struts to what is done. In order to replace the mount, the entire strut assembly comes out of the car and is disassembled. Then it is reassembled with new mounts. You'll probably be putting brand new mounts onto old struts that are well past their prime. If you later need new struts, all of the labor to remove & disassemble will have to be done all over. Its just one of those "penny-wise pound foolish" kind of things.
On there other hand, as noted, a little noise isn't a strong reason to do anything.
Are these the original struts? How many miles are on them? You would likely be very happy to get new struts for what it would do for ride & handling.
