That's not true. Pins {1,2} and {3,6} must be wired as pairs for longer
cable runs or you will throw the impedance all out of wack. At 10Mb you can
get away with just about anything Cat 2 will even work for short distances,
100Mb is not nearly as forgiving.

Why, Oh why, are there different specs? Are they used for different
types of wiring?

Or the T568A - we use this for some reason...
1 - wh/grn
2 - grn
3 - wh/or
4 - blu
5 - wh/blu
6 - or
7 - wh/brn
8 - brn

With extra wires leftover? WOW, I think I'll try it this way next
time. Run an anolog phone line too...

It really doesn't matter as far as the data is conserned how you wire
it. As long as it's the same on both ends (for the non-crossover cable)
it will work fine. The wires are special or anything.
Of course if you ever have someone who know's what there doing check it
out you may get a severe talkin to...
