Sally,
Glad to be of help. You've clearly grasped the basic principles, plus a bit.

With regard to resolution, there's only one thing you need to know regarding
images on screen:

MONITORS DISPLAY ONE PIXEL PER PIXEL.

On-screen inches, will vary from monitor to monitor depending on screen size
(e.g. 15" vs. 17" ) and resolution setting (e.g. 800x600 vs. 1024x768).

"Pixels per inch" is only a issue when printing to hard-copy (and preparing
to do so), though some image processing software (notably Photoshop) make
things a bit confusing by presenting image-resize and image-resolution
adjustments in the same dialog box.

I've had a look at your scanned letter and think you've decided on a very
good compromise between quality and file-size. It's a tough choice sometimes
between GIF and JPEG and the various settings in the two. The experimental
approach as you describe is really the only option, though some software
(notably Photoshop again) does make things easier by providing a live
preview of the resultant image as the settings are manipulated. (Hence no
need to save repeatedly). I think Paintshop Pro (expired versions of which
appear from time to time on computer cover discs) does the same. No doubt
someone can confirm, please.

Adrian
