Hi Joe
most Everio cameras come bundled with Cyberlink software - if you don't intend to do anything too fancy in editing your videos you can use this to convert them for uploading to Youtube.
Open the Cyberlink software and import your video, edit it as much as you want, then export it as an mpeg.
If you decide to get into some more serious video editing have a look at these:
Adobe Premiere Elements 7 - multiple audio and video tracks (up to 99), greenscreening, Picture-in Picture, lots of effects and transitions and the ability to encode and upload your video straight to your Youtube account from within the editing software.
Sony Vegas Movie Studio 9 Platinum Edition - multiple tracks (4 video and 4 audio), green screening, lots of effects and transitions.
You can download and sample the trial versions of these from the links above - see if either suits your purposes before committing money
hope this helps
