I'm wondering if you have looked at some of the fingering charts online. I'm not sure from your post what specifically you are having trouble with in working out the fingerings but there are several different formats online for fingerings. Some are downloadable and printable, while others are exclusively online where you click on the note you want the fingerings to and then it will show the basic fingering for that note. I think I have seen a pretty good chart on this site
Also this site does have an instructional section, although I haven't really explored it to see how helpful it would be for me. here's the link, and it does include a pretty good fingering chart as well.

If you want other fingering sites, I can pass those links along too.
Hope this helps at least some.
