You should be able to rename the catalog whatever you want using either the catalog settings or the block settings (for example, to change the catalog block title to say "Products".)

Personally, I'd just disable the /products page that ships with Ubercart. You can disable it from the menu and use another solution if you really want an all products page. That's just my opinion, though... I actually don't even know if anyone is using the default products listing.
