I live in the area and know the route well. It is largely very flat with a few very minor hills which is well suited for newbies and those just wanting a pretty ride. Riding along PCH (Pacific Coast Highway) is great and yes it is scenic. The traffic is a bit of a pain, but the shoulders are wide. As to rentals, check on the web at: http://www.superpages.com/yellowpage.../T-Long+Beach/. I live in Huntington Beach, so I am not too familiar with the bike shops in Long Beach.
