"Also is there any evidence to suggests that customers are more aware of/trusting of paypal?"
I think it's a wash. On the one hand, you have the people who realize it's safer than entering their credit card number on the merchant's web site. On the other hand, there are some people who just don't like PayPal or don't understand that a PayPal account is not required to complete their purchase.
If you sell low-cost items I'd recommend offering PayPal at least as an option. A lot of people think of money in their PayPal account as "play" money and will be more likely to use it for impulse purchases.
