Yeah, those should definitely do the trick.
These days I try to build core strengthening elements into as many exercises as possible. I like to do asymmetric exercises (i.e. one dumbell instead of a bar) with an unstable base (free weights, movement) when I can. I go for ab exercises that are good for the core, do pressups with my feet on a balance ball, and do a lot of very strenous yoga.
The yoga is very helpful. Most of the time when you do a deep stretch your back bends and twists, which indicates strain on the core muscles. Straightening back out works the core. I'm sure it's something that a lot of people would benefit from- I see people stretching but letting their cores collapse, and that's just passing up a great opporunity to add to the exercise.
