Novolog and Levemir are both availible in flexpens and both have cartridges that fit the Novopen 3 (a non-disposable insulin pen). Both Levemir and Novolog are insulins made by Novo Nordisk. Novolog is fast acting and has an action profile pretty much identical to Humalog. Levemir is a long acting insulin that has no peak and lasts between 12-18 hours. It's similar to Lantus except doesn't last quite as long.
You very rarely have to do injections on the pump...only if your bs is quite high, your pump fails, or you are taking a pump break. However, the infusion site insertion is generally significantly more painful than an infusion site insertion in my experience, so you might want to get comfortable with injections before making that move.
