Unfortunately, doing the pages of the catalogs this way makes the 140 pages appear to be very similar except for page title, description, keywords and the jpg alt text. There are a lot of navigation links that are the same on each page. So I assume that is why they are just a PR2 (Home page is PR4). The pages do show up in searches for relevant keywords.
How much alt text per jpg/gif does Google recognize? Is there an another way I can do this?
thanks
If G has indexed these pages then you are doing good so far.. The next step is to optimize these pages for keywords that get you better SERP results for the products on the pages. One way to do this is to use the ALT tag for the image. Someone smarter than me will have to answer how much text in an ALT tag G uses. A better way would be to add the text below the image in the page. Using style sheets you could keep the text from being too obtrusive (but don't hide it altogether using too small a font or white on white). This will give G some real text to index.
Best of luck.

That's not correct. PR gets passed between all pages in a site. In this case, which is the typical setup, the index page receives most PR from external links and passes that on to the internal pages.
Duplication issues are normally not related to PR. If you get penalized for duplication you don't have your pages with a PR2 in the index.
Also, PR2 for product pages is normally totally OK. If you do a solid onpage optimization and work good with linktext you should be fine.
Ranking is what counts, forget PR.
