your logo should always be a button that returns you to the main page.
each page should have a title (not "New Page 2").
adding buttons at the bottom for navigation is fine, and you might want to include a "Back" button on each page that takes you to the previous page. most serious surfers have their own way of navigating, but occasional users should be able to find their way around - keep it extremely simple for them.
all of the pics in current project and past projects should be clickable to show a higher resolution pic. i would stay with .gif files because they load faster (keep in mind people are still using telephone modems) and make them thumbnail size, then use higher resolution .jpg files for detailed pics.
i would watch using someone else's pics (the flamed fendered ford) if they are not a project you completed (misleading to prospective customers).
one way to make an easy job of the spacing is with tables (but i dunno if you can do that with frontpage, and it sounds like it might be outside of your coding ability). if you have a close friend (someone you can trust) that knows their way around HTML, i would have them look at it. i know for a fact that frontpage adds a bunch of useless code, and they might be able to trim it down for you.
good job.
