It'd be a good idea to make some kind of pocket or shelf on your cart (for tools, etc) so you can make adjustments on the fly.. this is particularly helpful during playoffs, as you might need to replace something on the field.. we stocked our cart with the most essential allen wrenches/etc last year and that paid off as one of our sprockets actually broke during the championship semifinals but we got it back on within 5 minutes..

Look at your bot (in our case we use extruded aluminium) and see which sizes of what tools you need the most. Go to some local tool store and buy 20 or so in that size, you can never have enough..

also, make sure you have something along the lines of a leatherman/knife, so many things can go wrong.. I still remember how in 2001 we discovered we had an illegal motor right as we were going on the field, so one kid spent 5 good minutes clawing at the motor trying to get its cables detached. One good hack with a knife would've done it.
