Bob,
Damien is right on with trying to get the electrician to
install a sub-panel. Have the electrican split the service going into the panel before it actually hits the panel and then get a new small sub panel. This is where your 20 a or better breakers go and then a separate ground is to be run to keep any ground loop from ocurring with the other junk on your main house panel. From the new grounded panel, you should be able to just run new wire to the dedicated outlets. That is the best way to go imo. As for your amps, 20 or 30 amp breakers will be fine depends on your desire. There isnt much of a difference. As far as running the new wire thru the old conduit... I cant say if there will be any noise.. I would tend to think not.. It is better than running the new lines across all kinds of other wires and whatever lurks in your attic or crawlspace!
Best of luck,
Joe
