Hi Rick_001!

About point 1:
I'd suggest you write a a function that translated urls to friendly urls.
so the link ../productid=123 becomes this link ../some_description_of_product-123/

Have apache Mod_rewrite installed and alter your .htaccess file accordingly to make the server understand which script to parse.

I've done it a lot and it gave me some excellent indexing stats for google.

Hope this helps!
