The lifts will feel really weird and your overhead strength feels weak due to you not ever being in that position. Basically, you need to get lots of reps in with light enough weight and drop ALL power versions of the lifts. The clean problem is probably due to timing. If you've not really done full cleans, then your timing for pulling under the bar will not be right, that's why you're catching high. Plus, only power cleaning will teach you to catch high. Again, drop all power versions and get your timing down with the full lifts, then you can start back to some days using the power versions.
I like Pendlay's beginner program very well for this. Keeps strength moving in the right direction while working enough reps to drill technique without focusing on weight on the bar.
