Payment gateway

First off Pro Sites is way better than Supporter.

I was wondering if there is a way i can enable both paypal and manual payment gateways for my site users. The reason why am asking this is because ecommerce is at the infant stages in Kenya, and therefore most people either don't have debit/credit cards that are enabled for online payment or they do not trust online payments.

On paypal is it possible to have a converter on check out so that the price I charge in Kenya Shillings can be converted to USD. For example if I am charging KSH6000 on check out it can display $60 USD.
