I installed Ubuntu on my macbook pro (8,1) a few months back using the rEFIt method (so it's an emulated BIOS). I want to give EFI mode a try. Unfortunately I have not found a clear guide on where to begin. I have read through scattered forum posts with hints about patches needed in the kernel and things like that, but I haven't seen any comprehensive guide.

I have seen this: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation#Single-Boot:%20Ubuntu%20Only

That appears to be what I'm looking for. If it is, then my question is this: Is there a way to do EFI and maintain a dual boot environment? The dual boot guides on the same page require rEFIt. If that's not what I think it is, where can I find info on how to install with this method?

I have 2011 (I think it's early 2011) Macbook Pro 8.2.
I'd had a lot of grief until yesterday, when I finally tried to install Ubuntu from the "normal" Ubuntu 12.04 (ubuntu-12.04-desktop-amd64.iso) instead of the MAC version (ubuntu-12.04-desktop-amd64+mac.iso).
The latter gives you rEFI (emulated bios) - you actually cannot get EFI from the MAC version iso, as it only supports the BIOS booting (sic!). How misleading!

I used the "normal" iso after I put an new, empty SSD drive to my MBP 8.2 and in installed in EFI mode and everything (with the exception of the wifi firmware which needs to be downloaded) has been working without any problems since.
