Hello Alexius,
Welcome to the forum :tu:
First of all you don't need so much components in your preamp.
I suggests to build DC coupled preamp,but here's the answers to your questions:
1.Yes, it would work,
2.By building DC coupled preamp, which also has voltage+current(buffer) gain.
3.Yes you do, capacitors have infinite resistance on DC voltage, hence they stop DC voltage to your pot(input buffer cap),and output(out buffer cap),also they shape frequencies.
4.In that kind of biasing, which is called voltage divider bias(or AC coupled follower), you polarize the gate to half of supply, which means that if you have +/- 10VAC signal, it will pass unaffected(unclipped),without it, if you have +/-2VAC signal it will clip the buffer.
5.Generally, more current, better the buffer, so none of them are good as buffers, but you can try 2SK170.
