HDTV TV inputs

I'm looking at the Olevia 37" LT37HVS.

What I'm trying to understand is, does it have the correct inputs available for what would be my immediate and future needs.

I would want to be able to connect a cable company set top box (Rogers in Toronto), a DVD player with upconverting capabilities and a computer.
I am hoping to initially use it with analogue cable, OTA HDTV and a computer with PVR (non-HDTV at this point) software. The computer currently does not have DVI output but that is a definite upgrade once I figure out exactly what is needed.

I'm not sure what the cable HDTV set-top box would connect to when I eventually use it. The HDMI connection?
I assume a splitter is used and one of the split signals goes into the CATV/antenna for analogue and one goes into the set-top box.
I understand the DVD with upconverting needs to use HDMI.
Would the computer go into the VGA or is it better for it to go into the HDMI.
