With the amount of stuff you have, I highly suggest you look at buying a friendly Video Editing Software package. What you will want, will depend on what you need to do. Here are some of your options.
If you want to do much editing of the video, I suggest you look at capturing it from your camcorder (via fireware), to your PC HD as DV-AVI or lossless AVI, make any edits, then encode and author to dvd. As far as DVD's, I recommend using either +r or -R dvd's (find out what your standalone players prefer), and use good quality media (Taiyo Yuden or Verbatim).
You can capture directly to MPEG2, but you will need MPEG editing software (and these are fairly limited), but available, and as long as you don't need to do real extensive editing, will do just fine. If you need to edit after it is on DVD (MPEG2), you can always demux the video, make edits, then re-encode it and will only suffer a very minor quality loss (won't notice it unless you have a large Hi-Def TV.)
Some good softwares to look are are:
For capture (VirtualVCR, VirtualDUBMOD, HUFFYUV)
Some good all in one's (Ulead Studio 10, Adobe Premiere Elements, Vegas Movie Studio)
Then there are ton's of indivual softwares which can be used for capturing, editing, encoding, authoring. Some folks like TMPGenc which is a good, decent priced software for encoding and authoring. Ask 20 different people, and you will get 20 different answers as to which is the best method. Most of them will do a great job for you. The only difference between a lot of them are the features, bells and whistles.
With the amount of stuff you have, I would highly recommend using Ulead Studio 10, Adobe Premiere Elements, or Vegas Movie Studio). If you watch, you can pick up any of the three of these for around $70.00 or less.
