I did what you're doing now starting a couple years ago. I am still a rookie but have learned some things which might be helpful.

this is the best forum I've ever found for helpful and expert information.

1. identify your zone and soil type when you post a question as this will impact experts advice.

2. do a soil test

3. learn about rootstocks and how they impact tree growth and viability for your zone.

4. do some research on what fruit you want and how much space the trees will require. then you can do some preliminary layout.

5. find out what pests and diseases are prominent in your area and give consideration to same when picking your trees.

6. start a big ring binder or file where you'll collect information, articles, nursery catalogs, and other stuff. It'll be a lot.

7. use the internet for research. there are vast amounts of info, much of it from various universities. Add that to the practical experience and advice you get here and you'll have a very good chance of avoiding any big mistakes.

You can grow apples and peaches in zone 5, and a nice orchard can be fit into a small, sunny space. Apples can be grown very close together, almost like tomatoes, provided you use a suitable root stock and stake or trellis them. Peaches, too, need not take up a lot of space. For great ideas on the apples, go to Google video and search U. Mass Fruit Advisor.

The nearby apples should help to pollinate your new trees. Not to worry about them. Tree trunks are painted white(using diluted interior latex) to avoid sunburn, etc. Better to wrap the trunks with aluminum foil, as this will also discourage the bunnies from girdling the trees.

Good luck. Misterbaby
