Broadband/ADSL Patch Cable

My DSL stuff came from Verzion and i see how to set it up. Service isn't going to be turned on until the 17th. It said if you need a longer dsl phone cable than they give to use a Broadband/ADSL Patch Cable which i see sells for $13.99 for 25 FT. The main phone cable comes in up stairs but the tower where the router/modem will be connected is down stairs. The sent a spliter for the wall jack which splits phone & DSL connections since DSL modem/router will need it's own direct cable form the main box upstairs. The phone setup i have now has main phone line branching off to feed all other phones and basement computer so will one filters at the beginning before the branches take care of all the regular phones lines?. The DSL modem/router will need it's own direct cable form the main box upstairs and since the cable will have to be longer than they sent will the 25 Ft. Broadband/ADSL Patch Cable be what i need?
Another issue came up as to what tyoe of plug used on the cable with RJ11 ends or RJ45 while radio shack says RJ-14 gold-plated plugs. I thought phone jack plugs were standard.
