I'm definitely no expert on this, but I'll offer some answers.
1) I'd suggest experimenting with various speeds of slo-mo. This can be varied in-game (a bit clumsy if you're trying to play at the same time...) or, more usefully, between attempts to extend the run. Maybe 10% for really difficult parts of the run that demand great accuracy, and 50% for general running (IIRC, 50% was pretty standard for TASMBF runs).
2) The batch file a.bat provided by Andrey shows how to do this. Naturally, you don't have to copy his exact system of filenames and so on. Stripped down to its basics, if you have a demo called, e.g. attempt1.lmp (no need for there to be a save in it; for the sake of argument let's say it's an HR demo), and wish to rerecord from part way through it, then your command line would be:
prboom -complevel 0 -file hr.wad -recordfrom attempt1.lmp attempt2.lmp
This plays back attempt1.lmp. When you reach the point at which you wish to start recording, press the join key and take over the controls from there. When you're done, you have a demo called attempt2.lmp. Repeat until finished.
To avoid having to watch the whole thing each time, you can add "-skipsec x" to the command line, where x is the number of seconds you wish to skip. Note that you can change the game speed while watching the existing demo, so that you have it running at the desired speed when you take over.
3) The mouse control seems to me no worse than normal in Prboom (i.e. pretty good, except for at the very start of a level).
BTW, I don't see any way to record a demo in parts (e.g. one level at a time, using saves) and then add them together, TASMBF-style. I tried recording a demo with MBF compatibility, but MBFLMPC didn't recognize it as an MBF demo. Also, Prboom rejects any attempt to make or load a savegame unless it is with -complevel -1.
