I'm a western PA guy, transplanted to eastern PA. So I can't help much with meeting up and showing of the ropes. I'm happy to share knowledge though.
As was said, around Pittsburgh there are a few stocked streams, that all in all aren't very good but can scratch the itch now and then. To your SE is the Laurel Highlands, with the Yough (which is very good, but humbling at times), and some smaller wild trout waters. 2-3 hrs to your east you get into central PA where our state's best trout fishing can be found (meaning wild trout in big water thanks to limestone geology). And to your north you have Slippery Rock, Neshannock, etc., which are also stocked streams but of better quality than the ones around the city.
My specialty area I know best in western PA is a little farther north, more like 2+ hrs. We have a cabin up there and I grew up fishing the area, and I know just about every trickle. It's generally a box outlined by Oil City, Marienville, Warren, and Corry, and includes the western side of the Allegheny National Forest. Generally the area consists of large stocked streams and small wild trout streams. All of the streams in the area are freestoners, and as such, the large ones simply get too warm in the summer for trout to survive, and hence no wild trout. But they are clean, with good hatches, good structure, and stocked reasonably heavily. As you get to smaller waters, they stay cooler, and wild trout begin to be present. In that area, generally west of the Allegheny River is flatter country, which leads to lower gradient waters, and the wild trout are mostly browns. East of the Allegheny is a little more mountainous (hilly by western standards), forested, and the wild trout are mostly brook trout.
I also lived in State College for 3 years and know central PA fairly well.
If you plan a trip to these places, I likely can't join ya, but I can certainly steer you in the right direction. Feel free to PM me.
I have fished Idaho, Montana, Wyoming, etc. I have a feeling what you'll gather is that what we call "big" and "small" is very different. Our "big" waters would be considered small by western standards, and our small waters little more than drainage ditches by western standards. That said, we still have a LOT of water. It's just smaller country. There's a lot more valleys, and every one of them holds a small stream.
We have over 3000 wild trout streams in the state, and hundreds more that are stocked. In the west, they thought nothing of travelling an hour to fish a stream, or even a different part of the same stream. Here, in the better parts of the state, an hours drive means you're passing 100's of different streams. But Pittsburgh is NOT one of the better parts of the state, in terms of trout fishing, anyway.
