Pants are considered as part of raingear, but you don't have to spend lots of money on them. Gore-tex is not a requirement for these, rather just a good pair of wind blocking pants work. Rain pants can often double as in camp pants, so you might look for ones that have a reinforced seat.
One big misconception about gore-tex is that it is a fabric: wrong. It is a thin membrane that coats the fabric making the fabric "breathable". Gore-tex is only one breatheable system on the market; there are many other brands out there at a cheaper price.
As to going "gore-happy", in my opinion, you don't need gore-tex boots and gloves. No matter what I do, my feet will still sweat and if you treat your boots correctly they will be waterproof. So don't be swindled by salesmen saying "gore-tex" and expecting you to swoon. I suggest breathable jackets, maybe pants and possibly a hat. That is just my opinion from what I have heard and from my experiences.
