Laura, another modification that most serious riders make is suspension upgrades. Out of the box, the Bonneville and T100 suspensions are adequate, not spectacular by any means. Upgrading the suspension transforms the bike. The ride is less harsh, the bike plants better in turns, and the overall handing greatly improves. Both of my T100's have Progressive springs in the forks and upgraded rear shocks. As you get to know your bike and experieince some miles on it, you might want to consider upgrading the suspension - if the previous owner has not already done so.
