conversion options from Canon 650D to youtube.

hi,
new to video editing here, so on a steep learning curve.
Have a canon 650D and want to upload HD videos to youtube, experiencing problems and 'warnings' about video/audio synchronicity when uploading to youtube.

Have tried
- microsoft movie maker [ok, it was easy to use, windows, free and not very powerful but nice user interface]
- vlc - used gui mode and command line interface.
- ffmpeg - gui mode only so far, looking at commane line interface.
- lightworks.
Currently working on windows 7 platform, also have a ubuntu desktop that I really need to start using again.

I'm leaning towards a system that uses scripts or queueing to shrink the large videos overnight, then do the cutting in a gui environment to pick the right start/end points. microsoft movie maker was nice for this but it seemed to be the cause of mis-matched timing problems. Given my videos are of dance performances, perfect timing is important. [to the extent some professional teachers/performers/artists request their videos not be published if the video editing/youtube cannot get timing right.]

Youtube video guidelines don't help me a lot with choosing the correct settings to use. Mostly because I'm not sure how to choose the correct settings in the package I'm using.

My video editing at moment is limited to cutting start & end points, adding a title page at start and a image at end for the events I am filming. Once I get the hang of this will look at more advanced cuts and mixes and whatever effects I feel are desirable. Would be nice to work on correcting exposure / white balance issues but working on improving my selection of camera settings and lighting at the venue.

Any pointers out there for the youtube settings? I read somewhere video bit rate should be limited to 6000 bits/s due to youtube not using higher rates and excess bitrate possibly contributing to errors. A friend mentioned audio/video timing issues would probably be due to mismatched codecs or incompatible codecs with youtube requirements.

I think I really need a good tutorial on explaining the basic settings - would love to hear from someone who has a system working, particularly on the settings required for youtube.

VLC looks like it has some powerful options at command line but documentation on how to use is scarce.
FFMPEG - similar - but still reading up on this.
lightworks - friend reccomended this but I cannot get my camera video files to load.

My camera video files as analysed by 'mediainfo'. Other video settings on the camera will produce lower resolution/different frame rates etc. Pretty sure the output below is the highest video quality possible with this model camera.
MPEG-4 (quuicktime)
video stream AVC
audio stream pcm
overall bit rate 47.0 Mbps
video stream 45.4 Mbps, 1920*1080 2 23.976 fps AVC baseline @L5.0
audio stream 1536Kbps, 48.0Kbps, 16 bits, 2 channels, PCM (little / signed)

I'm leaning towards opensource software but curious about commercial options - if only for ease of use. Featurewise the opensource packages appear to have more features than I need/can-use.
