The headset wrench will be fine when you want to adjust or replace the headset bearings on the 10 speed. With your variety of bikes I dont think there is anything in that kit you wont need. However check with Nashbar that it includes a cassette removal tool because that is something you will want in a hurry when you need it (replacing a rear spoke). Freewheel removal tool for the 10 speed is something you will have to buy separately because there were so many varieties - start looking now.
