The only time I wear gloves is when it's cold. My order of purchase would be:
1. Helmet.
2. Flat repair kit with frame mounted pump. Or a CO2 inflator, but a frame pump is still a nice back up. Always carry a spare tube, it's easier to patch at home.
3. Underseat bag.
4. Bike multi tool with chain breaker
5. SRAM quick remove link (for the best and easiest chain and sprocket maintenance, the chain is off the bike and in a mason jar with paint thinner or other solvent of your choice)
6. Bar ends
7. Bike shorts, either bib or regular.
