"I just want to know the best way to run the rectifier as SS instead of tube. Will the WZ34 (450ma) be a good choice?"
I don't think so! Aside from the switching noise issue already mentioned, the forward drop characteristic is dead wrong. Look at the 5V3 data sheet. Notice the 47 V. drop. As vacuum rectifiers go, the 5AR4/GZ34 exhibits a relatively small forward drop.
Mike Samra gave you good advice about high PIV Schottky diodes. They don't generate reverse recovery spike noise. To use SS rectified B+ successfully, you will have to rework the PSU filter. IMO, a reasonable approach follows. Use a smallish 1st filter capacitor. Follow with a choke whose inductance is substantial. Then use a large reservoir. capacitor. The filter is cLC. You adjust the value of the smallish 1st cap. so that the minimum value which keeps the B+ rail voltage up is used.
