Well the first 3 are easy enough
1. You can wire in a .25 mfd 630 volt capacitor and replicate the windings as on the original. Actually the set will probably play OK without the windings. Rather that than have a possibly dangerous leaky capacitor there.
2. The .001 you have on hand is probably OK. But you can get .0015 caps easily enough.
3. The 22 mfds you have are OK to use. A larger value would cut down some on the hum, but I wouldn't go above 40 mfd for fear of shortening the life of the rectifier.
The remaining questions I think will be picked up by the more experienced.
If the alignment has not been performed, you should do so with a signal generator. Then you can get the stations to come in where they are supposed to be. Whenever you do a wholesale replacement of capacitors, an alignment is in order.
Best of luck on your venture. Quite a few of us on this forum also build and fix guitar amps.
