If you edit the RTF using NotePad (
not WordPad) you can adjust the meta data manually.
For the title, the string to look for is called (imaginatively) "{\title " and is followed by the meta data title.
You can edit those directly in Word via the document properties, but Word bloats files so horribly, and WordPad strips out the meta data (which can actually be handy if you just want the filename to be the title that shows up on the Reader).
There are details on manually editing the meta data
here.
