Hi,
Step 1 - If the wireless router has an adsl port on it, then you should be able to just plug the cable currently going from your phone socket into your USB modem, into that port.
You'll probably want to do steps 2 and 3 with a physical connection to the machine, so if your computer has a network socket, and you've got a network cable - plug that in to the output socket of the wireless router to do these.
Step 2- You will need to access the routers control screens (I'd suggest you google the manual to find out how to do this) and make sure that the settings for it's internet connection are set to the same as your USB modem's settings.
Step 3 - You'll also want to set up the wireless settings for the router whilst you're in there - choose an SSID and security key, etc.
If your wireless settings on your computer(s) are correct you should then be able to access the router over wireless and firewalls, anti-virus software, etc permitting you should be able to access the internet.
Hope this helps
Sparks
