When I do scales for example, I find that as I move down to the higher strings I get feedback from the upper strings vibrating. What are some ways to make the sound clearer without feedback?

a noise gate/suppressor?

Proper muting technique and standing further away from your amp generally do the trick but if you're muting well and standing on the other side of a reasonable size room and you're still getting feedback then a noise gate is in order; I recommend the ISP Decimator.
