Shopping Basket & Customer Logins

At the moment, my website glowman.co.uk uses basket2go, which isnt ideal as it has a poor interface and the payment processor Nochex has the £100 limit.

Ideally i would like to run my basket pages off my hosting, as currently all of the basket pages are hosted on basket2go, allthough the pages look like mine, allthough i still want to use nochex

I would also like to run a customer login to remember customer details and add them on the checkout pages. I havent been trading long, about 2weeks, but a rival/friend has everything im looking for. Would this be a good idea or am i goin too far for a new starter?

Cheers!
