If you have to replace both and you can only replace one now, replace the cam position sensor first. If it goes completely out, the car will not run. It may not run as good without the new hose, but it will still run.

Something to think about, though, is that the hose really should not cost very much. Depending on which hose you need, it runs from (as of this post) $5-24 on RockAuto.com. It should be fairly accessible and could most likely be replaced without issue by yourself, even if you don't have any mechanical abilities. The camshaft position sensor shouldn't be overly expensive either, but it is going to cost a lot more than the hose, that's for sure. I'm seeing it listed for ~$50 on RockAuto. These are usually a little bit harder to replace, but since there is only one connector and one bolt which holds it in place, is usually not hard to replace, either. If the shop does it, they'll triple the price of the sensor, and charge an hour's worth of labor, so looking at ~$250 to replace (total SWAG1 on my part, but most likely the case).
