Solve Canon C300 MXF to Adobe Premiere Pro CS6 issues on Mac OS X Mountain Lion

At the moment, I'm looking through a rough assemble I've done on a PPro sequence and then the playback will start getting choppy. The only solution seems to be rebooting PPro, which is obviously very frustrating. The footage is C300 files, stored on my RAID. Why is this happening? My system details are as follows:
My system details are as follows:
MBP early 2011, 16GB RAM, 512 GB SSD
6TB Pegasus R6 RAID connected via Thunderbolt
30" ACD
Mac OS 10.8.2, PPro 6.0.1
Another issue I had which is more annoying that anything is that when I imported the rushes from my C300, PPro decided to import a fairly long (80") interview as loads of separate .MXF files RATHER than joining them together, which FCP seemed to have no problem in doing...How do I sort that out? "
