meegosh,
the xmas light bulbs might work, but they might draw too much current (they're meant for AC power, rather than the AeroAce's DC current). but, give it a try

you could stop at a radio shack and ask them about the proper resister for your needs. i'm sure they'll have one there too for a cheap price.
all single cell lipos have a opperating voltage range from 2.9 to 4.2 volts. too much above or below those numbers can ruin the cell.

edit: just got an email back from spinmasters about replacement parts (props!). they said they didnt have any yet, but hope to by december. just thought i'd pass it along.
