UK Fasthosts and 10mb SSL

Hi

Still a little confused over this issue. I can provide 5Gb of space with unlimited traffic (load balanced) with SSL to my customers ** EDITED PRICES **. This is using ** EDITED ** .

Good points: PHP runs as a module, not CGI, low cost, huge traffic and space, 300Mb MySQL database included, Traffic Driver included, 5 AV and AS POP3

Bad Points: SSL is inlcuded BUT is run through a Windows server and is only 10Mb.
For a site running, say, 3000 to 5000 products, is this enough?

I do understand that I need a standalone certificate so I am looking at Comodo.

Basically, whcih parts of the site would I need to upload to the SSL server and how much SSL space would I need ideally?

Thanks
