Can you use Apple Mail program Rules and Gmail filters together?

The gmail filter would happen first (on the server) before the message reaches Apple Mail (the client) so in that sense gmail could override. I would use one or the other (probably prefer gmail since it's on the server).

I use several Gmail accounts, in addition to some .mac and .me addresses, and I prefer to receive all of those messages in one place -- on my iMac using Mail.

For me, I've turned off/disabled as much of the filtering and other default "enhancements" Gmail tries to apply through Settings. This means going through the tabs one at a time to minimize adding stars, marking something Important, turning off Desktop Notifications, assigning to Categories, creating all of those separate inboxes/folders, etc.

By doing this, Mail on my iMac just accesses all of my email and then applies any rules/filtering to everything sent to me. I agree with DarrentBrackett about using one or the other, but I prefer using Mail since I only need to create a filter/rule once, it's easier to modify this way, and I don't need to worry that Google/Gmail isn't showing me something in Mail because of a misapplied filter or rule.
