Your cardio sounds fine. As long as you're pushing yourself and enjoy what you're doing, you are on the right track. I would recommend changing your strength routine a little. You should be working your major muscle groups a minimum of twice a week. So I'd suggest doing a full-body routine 2-3 days per week instead of a split routine where you're only working once a week. You should be able to get a good full-body workout in 20-30 minutes, so don't feel like you have to do tons of exercises for each muscle group.
As far as weight goes, don't be afraid to lift heavy. You should be using a weight that fatigues your muscles in 8-12 repetitions, 1-3 sets of each exercise. The last rep in the set should be the last one you can do in proper form.
I would also recommend having your body fat tested. You're at a healthy weight for your size, so that test is going to tell you if you have more fat to lose, or if you're already in the healthy range and just need to focus on building muscle instead of the scale.
Hope that helps,
