We'll start with a few questions, since there is actually no "right" answer to this question.

1. Does your TV have an HDMI input?
2. What DVD player do you have? Does it have an HDMI output?
3. Does your HD satellite receiver have an HDMI output?
4. What CD player do you have?

In addition to responding to one question with a bunch of other questions, I'll toss in a few actually useful bits of information.

First, you will need to have some sort of analog video connection between the 990 and your TV so that you can access the setup menus. This can be a component connection if you are using component video sources, but if all of your video sources are HDMI/DVI you can get by with just a composite video cable to the TV.

Second, the 990's DVI switching can switch HDMI video sources to an HDMI display, but it handles video only and is a "passive" switch (no on-screen display added and no transcoding of analog video inputs to the DVI video output). You will need to connect a digital audio cable from both the DVD player and the satellite receiver. Either optical or coaxial will do.

Lastly, the CD player can connect via analog or digital. Depending on the player, it may be worth trying both if the analog section on the player is really good. If it is an older or budget player, though, it may be simpler to just connect a digital audio cable and let the 990 handle the conversion to analog.
