You have several options:

1. Pay Verizon for their Broadband Access tethering service. They give you software, that you must run, and that performs a function that Windows' built in networking does better. But it's fully supported by them. Personally, if I used Verizon for my primary Internet, I'd get an aircard and not tie up my phone. But I only tether occasionally, so I use option...

2. Install the WinMo Internet Connection Sharing app on the phone. Windows Mobile includes this, but Verizon removed it from their stock ROMs (presumably to convince you to pay them extra for Broadband Access). One installed, you plug in the phone to your PC (with Activesync installed) with a data cable, start the Internet Sharing app on the phone, and hit "Connect". Google for "Omnia ICSinstall" to find it. Once you have this on the phone, you can get other programs like WMWifirouter, the HTC Internet sharing app that has been ported to the Omnia lately, or, if you like getting your hands dirtier, ICScontrol, to turn your phone into a wireless access point and more.

3. Use a tool like QPST to hack the phone's radio firmware to allow it to get on the 3G network as a "dumb" dial-up modem. You have to install the Samsung USB modem drivers for this. This used to be your only option, but today option 2 is much easier, and I wouldn't recommend this any longer.
