My wife and I visited central Portugal last September, including some of the towns mentioned by you, and others which may be of interest to you. For details and photos of our visit see the "Portugal" section of Our Travel Journals: http://www.evcal.org .

just another detail: by coincidence I came across a note that the railway-tracks between Lisbon and Evora (to be precise: between Vendas Novas and Casa Branca) are currently closed for electrification works (which will take some time), transport is replaced by busses, thus you'll merely have to choose between cp-busses and rede-busses ;-)
