My post got lost, .003 almost certainly a paper capacitor. You can use 630 VDC mylar or poly capacitors to replace just about any paper cap in old radios, save the one from the plate of the output tube. Use 1000 VDC type for that one. I keep 450 VDC electolytics around, because, again, they can be used for almost any set with equal or less B+.
Micas are generally below .001 mf, or basically less than 1000 pf. (same!) Generally OK to leave alone, but seen enough bad ones that for a simple set with only a few of 'em I replace with recently manufactured 500 volt silver micas. I also routinely replace carbon resistors whilst doing capacitors, easy and cheap enough to do. Result is long term reliability, easier alignment, and usually much better performance. I'd order all the stuff you need at once to keep shipping delays and costs in check. Lots of good places to order online mentioned all the time here; Mouser, Digikey, Jameco, Just Radios and lots of others.
Best!
