Ok, just to offer some terminology and clarification to make this all easier to communicate in the future:
What you call a "Telephone Switch Panel" is actually a "110-style Wiring Block". (Never use the word "switch" unless it is a powered piece of electronic equipment with switching capability, or a physical lever used to turn something on or off. Any other use only leads to confusion)
The "wall plates with clip-on sections" are actually called "Keystone Wall Plates with Keystone Jacks." For the most part, they all follow the same standards, so any keystone jack will fit in any keystone wall plate, but some manufacturers do not follow the standards. The best thing to do is find out what brand plates/jacks you have (it s usually stamped into the back of the plate, and jacks), and buy the new jacks from the same manufacturer. This will ensure a good fit and avoid issues with a too-tight or too-loose fit. The most popular brand, and the one I stick with, is Leviton.
To follow the RJ45 wiring standard, you should be wiring all 4 pairs in your Cat5E cables into the jacks using the proper color order. If you do not know the proper order, look up the 568-A and 568-B
wiring standards. There is a lot of debate which is better, but through all the testing I have seen, it really makes no difference which you use. The only thing you need to make sure is that once you choose A or B, to use that standard for EVERYTHING. If you decide to purchase a Patch Panel
it may only be labelled for 568-A or 568-B, so the rest of the wiring in your house will have to match that patch panel.
In a pinch, a Cat5 cable can be used for TWO network connections (at a max speed of 100Mb/sec each) by only wiring two of the pairs in the cable into each jack on both sides of the cable (four jacks total, two jacks on each end of the cable). That is why calimark asked if you were using 2-pair or 4-pair. As long as you follow the 568 wiring standards above, and you use Gigabit switches and NICs, you should get gigabit speeds from your Cat5E cables. When he said "gige" he was talking about Gigabit Ethernet (commonly referred to as "GigE"), it was not a mis-spelling of the word "gauge."
