answered you in PM, but figured i'd post here as well for others looking for an answer

Adobe Encore or Toast are your two main choices for authoring to Blu-ray...Toast has more limited options in regards to menus and whatnot, but is a lot cheaper $

editing HD-format files [like your AVCHD files] is possible with any of the NLEs available -- Final Cut, Adobe Premiere, and Avid being your primary progs...encoding for blu-ray can be handled by the video encoders associated with the above NLE suites [also Sorenson Squeeze]


so there's numerous options, but the two most common workflows [not including Avid] for authoring blu-rays on a Mac would be...
Final Cut suite users: Final Cut > Compressor > Adobe Encore or Toast
Adobe Production suite users: Premiere > Media Encoder > Encore
