Sony NEX-VG10, my iMac and Premiere Pro – not working!

I recently purchased the Sony NEX-VG10 and am really excited about it.  i have run into some serious problems capturing the footage, though.  I have a 2010 iMac, am running OSX 10.8.2  Mountain Lion and use Adobe Premiere Pro CS6 to edit.  I’ve discovered that the files on the camera are .MTS, a file format with which I am unfamiliar (not surprising, I’m not exactly a newb, but the past few months is the first time I’ve started editing seriously – I am more a writer/director/producer and could do basic stuff with FC7 and Prem Pro – now I own my own production company and am getting down to the nitty gritty).  But I have found that

1. I can’t capture using bridge, it doesn’t recognize the file format.

2. When I plug the camera into the computer and go straight to the files, I don’t even get individual files.  All the information is contained in what looks like a Quicktime movie, but isn’t recognized by Quicktime or any other program as anything.

3.  When I go into the camera files using the import function in Premiere Pro, I find the individual .MTS files – which say they are Unix Executable files (no idea what that means), I can import them into PP, but the quality is atrocious.  Grainy and pixely.  Even when viewing them in full res playback mode.

4. I bought Bigasoft Total Video converter (wicked cool program).  I import the files using PP, then go find them in this program, and convert them into .mov files – the quality is still atrocious (not surprised, as the .mts files look cruddy, what could I expect when I converted them – but was worth a try).

I need to capture these files in full quality (oh – the file information says they are in 1920 x 1080 (1.0), so it’s not like I filmed in a low res. 

The software that came with the camera is for PCs, I’ve searched for answers to these problems, and although I’ve found similar, I can’t find anything that actually helps me.  Can anyone out there tell me exactly what to do?!?  I would be most appreciative.  My new company’s success depends on it!
