Hmmm...let's crunch numbers:
40D - $1299
50 f/1.8 - $69
Total - $1368
30D (used) - $800 (roughly)
50 f/1.4 - $285
Total - $1085
To me, going the 30D + 50 f/1.4 is the better choice. The 30D is a solid performer and the 50 f/1.4 is a phenomenal lens. With the leftover money, you could get a CF card and maybe extra towards a 430EX.
Bodies come and go but good glass lasts almost a lifetime. Go with the glass. You can always upgrade to a 40D later.
Good luck
