Sorry, I don't know the default configuration for the HTS (as far as speaker sizes and bass management, etc.).
The first or second generation DVD players used to be able to play video in "progressive mode". This just meant that it output a 480p progressive signal instead of a 480i interlaced signal. If the HTS is showing video from a 480p progressive movie/source, it will not allow the on-screen menu to come up. If you do not have anything active connected to the video inputs, you should be fine because the HTS will output 480i by default. The converter should be able to convert the 480i to HDMI and your Plasma should accept the 480i video just fine.
Make sure you connect the cable to the composite RCA output that has "OSD" printed next to it. That's the only one that will work.
You will need a remote of some kind to being up the on-screen menu (by using the MENU button on the remote). It is not accessible from the front panel of the unit.
