Welcome to the Q&A Forum

We had the same issue moving our site from nopcommerce to magento.  The structure of the site in regards to category and even file extension (.aspx to .html) changed.  We had over 2000 products and to create redirects for all of them was quite a bear. What we ended up doing was to look into Google's rankings of our top 500 pages and focus on getting those redirected initially.  Checking both the supplemental and primary indexes helped us to figure out which ones to do.  I also ended up using excel and its formulas to create the redirect links enmass and then copied them to my .htaccess file.  Also too, if you had a specific directory where your ecommerce site use to be located ( we had /Store/) create that directory and place your .htaccess in that file with Symlinks turned On. This seemed to take care of everything for us and helped us to focus on links that were actually indexed.

Always keep the phone number there. It's not going to give any SEO help, however it's good practise for marketing

It's worth considering it anyway.

Content, alt tags, anchor text to internal pages are always favorites : )

Sure, every site I write is free of errors : ) I do have some with warnings, but none with errors.

Duplicate content is no longer a penalty reason - google will only decide who of them is the original source and list in the search engine results the appropriate source. Sometimes however the one that in fact is the one that did copied the content is getting listed first and the original source is getting down in search results.

No offical testing here but, ANY thing can have behavioral SEO benifits that could lead to more organic conversions.  But do they have algorithmic value? Probally not, but I will conduct some studies into this in my free time. But I would love it if we can find some legitimate sources for this topic, digging initiated.

What is interesting is the with CSS3, the standard has the ability to add custom fonts and the browser will load those on the fly. So things will get really creative soon. I like Palatino Linotype. But there are not many choices out there : )

How long has this been? I noticed a while back that report cards don' t update quickly. Put the call ticket in as David suggested.

If there was an "easy way" then everyone and anyone would be ranking #1 in Google...and eventually competition would be so saturated there would be no point in having a website at all! Good things come to those who work hard, stay committed to their vision, and can learn and adapt to change!

I am fairly sure that Pagerank is now constantly updated, it may well be that they only adjust the visible pagerank every three months though. I can only say this next bit speculatively because I don't have the data (I would love to see the periods and numbers for the site above), but the cap itself might be a somewhat fluid idea, pages may be retained in the index as they are discovered but get pared back to their "hard cap" periodically.
