Internet->Phone->Router->Network ???

[Firsttimer]

I am trying to get the following configuration to work. I live in a area that does not have any source of hi-speed Internet, just dial-up. I want to use my phone's Internet and share it with all of my computers on my network, all computers at the same time.

My equipment, HTC Imagio phone with WiFi software router and currently Verizon tethering via USB or WiFi. Several Belkin and D-Link 802.11g WiFi routers. Lots of Cisco routers and switches (2500 & 2600 series routers). Three laptops running XP, Vista, and Windows 7. Two HP Proliant DL585 servers with two NIC's and running Server 2003 Enterprise. One Dell desktop with 2 Wifi cards and one NIC, running Vista.

The problem is that my servers and Cisco stuff is on one side of the house and my office is on the other. I am in a wheelchair and cannot run a wire between the two sides so I am using WiFi.

I need my phone is my office where I am working so I can answer calls yet I want my desktop. laptops, and servers all to be able to access the Internet as though I had DSL or Cable Internet.

I am studying for my Cisco CCNA certification and could really use this help so I can do the many labs I find. Ultamitly I am going to hook the phone up to a Cisco router then to my lab network. Obviously I cannot hook the phone up directly to a Cisco router and there lies the issue. After buying all of the servers and routers, I can't afford to get a USB of PC Card from Verizon. Besides the cost difference between the smart phone plan and a data only plan is too much and for now I have true unlimited data usage since I am an Alltel transplant.

Any ideas on what I need to setup, do to make this work?
