1. Yes, outbound links can support or even improve good rankings.
2. People clicking on an outbound link and not returning did not find what they were looking for on your page anyway.
3. If rankings go up, then total traffic goes up. "Losing" a certain percentage of visitors to the outbound link is not really a problem because it's a percentage of a higher number. So you still get higher sales.
4. Just because people click out doesn't mean they don't come back. Linking out to a valuable resource can be much appreciated by the end user.
Also agreed with StickyNote - if your visitors see the page as a true resource, they're more inclined to link to it - that's good for your site, as well as being good for people seeking real information on the particular subject.
