Hi Ffliwt.
I think that your best bet by far would be to join Schubertline, buy at least two large folders and lots of plastic pockets and go wild! A subscription costs about the same as one decent song album and you will be able to print out hundreds of songs to suit your voice in whatever key you like at the click of your mouse. You may well find lots of songs there that you have sung already and you can print these out too so that you have a repertoire list to have fun with. The only ones that you should sing in the original keys are arias from opera and oratorio.
I second this notion, I've printed out the Brahms and the Wolf songs, as quite a few turn up on various diploma lists, and apart from one or two pieces of Brahms I had nothing of theirs. (I'm currently waiting for the printer man to come and change the imaging unit in my spangly copier/printer, before laying into them again)
_Generally_ you can get away with lowering by a semi-tone for baroque opera/oratorio pieces.
Alternatively, Hal Leonard books are quite good value eg: Arias for Sopranos and Oratorio Anthology - Soprano, could be worth considering. I think musicroom might list the contents and amazon might be cheaper.
