First, I suggest you ignore the virtual channels, because it tells you nothing about what frequency the station comes in on.
Look at the real channels. 2-6 is VHF low, 7-13 VHF high, and 14-51 UHF. You want KJWP (not KJWT?) ch 2 and KPVI channel 6, so I'd choose one of the Antennacraft HD series
http://www.antennacraft.net/Antennas...llChannel.html and point it at 132 magnetic. Note these are big antennas - the smallest HD850 has a 7' beam length, and the largest is 15'. You need the length to pick up those VHF low stations, because of the signal's long wavelength.
I expect that the larger you go, the more stations you'll get. Your report isn't great - you have a lot of stations at one heading (that's good) but none of them are line of sight. Realize that buildings and trees will cause problems with the signal, so if you can choose a location that has a direct shot to the horizon at 132 your results will be better. Usually more height is better, so go up as much as you can. I'd mount a mast on the roof with the antenna at the top of that.
An attic antenna is often problematic. Roofing and contruction materials attenuate the signal, and you don't have a lot of signal to waste. Stucco is a problem, because the wire mesh used to support the stucco is a barrier to radio waves. And stone is ... dense as stone. And these antennas will probably be too large for an attic.
However, if you are fortunate that the house is oriented so that you can aim though the shingle roof at 132 magnetic, and there is room in the attic for the big antenna, and there are no pipes/vents/chimneys in the way of the antenna, an attic installation
might work. But you can't aim through the stucco sidewalls - you want only roof sheathing and asphalt shingles between your antenna and the outside. And from there, a straight shot to the horizon - no trees or buildings in the way.
How about a mast in the yard? It's not on the roof, and you can get some decent height with a little effort. Won't be cheap. but it seems like your only other option. Just an example -
