Welcome to SMF from someone who's been here only a few months. You will find no better place to learn.
As for your cherry tree, I don't have a clue what to recommend. I think the recommendations might depend somewhat on the equipment you are using and the results you are looking for and the kind of meat you are cooking. Many years ago when I first got beyond grilling meat on a briquet fire, the first thing I tried was cracking hickory nuts from the tree in the back yard (lived in NC at the time) and sprinkling them over the charcoal before putting on steaks and closing the lid on the unit. That simple act got me started but I didn't really get into smoking much until late last year when I bought the MES40 at Sam's.
If you are using a charcoal grill, there are lots of different ways to make smoke. While I was at WallyWorld yesterday, I saw a little metal smoke box that I might go back and get for use with my grill. I use the AMNPS with the MES, but I'm thinkin' that a smoker box might give me 'smoke' options for grilling that I haven't yet explored.
At any rate, . Pull up next to the fire and swap some tales with us.
