Apple Sauce Help!

So we got some apples from our ward garden (they have a ton there and it seems like no one has picked any). So today I thought I could dry some and make some applesauce. I tried making some applesauce today. If anyone has made it and will give me some tips, I appreciate it. How long do you boil/simmer the apples for (it seemed to take forever and still didn't seem long enough)?

Also, if you have any tips on drying apples (in an oven) before I try. I want to try making apple juice, but it seems like you need a juicer to do that and I don't have one.
