Hello, and welcome! Thanks for being a premium member.
YUY2 is how you should capture. Lagarith is fine. it supports same color spaces as
Huffyuv (YUY2 for 4:2:2, YV12 for 4:2:0) and is a bit more efficient at compression, so your files will be a bit smaller. Read this and continue to refer back to it.

You should be able to keep the avi file in 4:2:2 (YUY2) the whole way through. You see a lot of Avisynth script examples using ConvertToYV12. That is necessary for things such as temporary use of the Histogram commands so you can analyze your video, of which there are many example threads showing how the histograms can help show you how to redo your capture for proper levels, or fix in post with Avisynth. At least older versions of QTGMC required ConvertToYV12, because it did not support 4:2:2 color space. I have read that this is no longer true if you get a more recent version of QTGMC. Of course, there's a lot of avisynth plugins required to use QTGMC. Or you could try Hybrid if you are not into a lot of script writing. Not sure what version they use there. I think there was a thread recently discussing how you can keep 4:2:2 all the way through, so long as you don't need any Avisynth plugins that cannot handle YUY2 or YV16 (4:2:2).
Direct Stream Copy is used to for things like frame edits only, or remuxing new audio file to existing video. Those are cases where
Virtualdub will not apply any
Virtualdub filters or Avisynth filters/commands to your video. It does not re-encode any video.
Fast Recompress is used when you are not using Virtualdub filters, not to be confused with Avisynth filters. Avisynth filters/commands are called from the .avs script file. When you do a Save as AVI in this mode, it will save to whatever settings you specify in Video -> Compression. Also setup Video -> Color Depth with Decompression Setting of Autoselect, then Output format to compressor/display to YUY2. I believe that setting tells it how to read the file into Virtualdub. The Compression setting is what settings to use to save the file.
Full Processing Mode is necessary if you are using Virtualdub Filters (Video -> Filters). Virtualdub filters work in RGB color space (i.e. completely uncompressed lossless files which are about 3x bigger than
Huffyuv or Lagarith lossless compression). Virtualdub will process anything in your avisynth script first, then it will process the list of Virtualdub filters you have. When you Save As AVI, it uses the settings previously discussed to convert back to your format of choice. You can use both avisynth and virtualdub filters in the same step, so long as you are in Full Processing Mode.
Use Avisynth crop function to trim out noise on the edges, and the addborders command to replace the same number of pixels you lost with the trim function, so that your output has the same 720 x 480 dimensions. Look them up on this forum, or
https://avisnyth.nl. There are some restrictions on some values having to be divisible by 2 or 4, so don't use odd numbers when cropping.
I don't have Adobe. If you want to make frame cuts, it can be done in Virtualdub, but can be a bit clunky if you want to merge two files together. But it is ok for deleting ranges of frames. Or you can use the avisynth trim command. For example trim(20,1000) ++ trim(1050,0) if you want to trim out frames 0 to 19 and 1001 to 1049. You can chain as many of these trim commands together as you need. You can also combine sections of multiple files together with avisynth, such as v1.trim(20,1000) ++ v2.trim(1050,0)
Forum often cites software such as Mainconcept, ffmpeg, and Avidemux (certain versions, search forum for more) when converting to MPEG2 or MP4.
Hope that helps answer your questions.
