You're halfway done with the debt elimination. Keep up the good work.
The student loan debt will get in your way a couple of ways when you look to finance a house. First, your debt to income ratio will be higher than without the debt, so you'll be able to qualify for a smaller loan with the debt than without. Second, you'll have the student loan payments in addition to your mortgage. This may wear on you.
I'd look for ways to make extra money to knock out those student loan debts ASAP. The rates aren't horrible. That, and I think there is still some time before the housing market bottoms out, so you don't need to rush into the house.
If you can handle the entire debt load (student loans + mortgage) then if you save up for the down payment, that money isn't being used to pay down your student loans, and paying your students loans off won't get any easier when you get a mortgage on top of that.
