The bridge rectifiers I'm looking at on Mouser.com have spade terminals:

Mouser part numbers: 512-GBPC12005 12amp 50v

512-GBPC36005 35amp 50v

512-GBPC35004 35amp 400v

The difference in cost is very small, so would a part with a higher rating be a better choice, considering a larger transformer could be used in the future?

Is current loss a factor in rectifiers, thus making a minimally rated part the only reasonable choice? Are all of these too big?

Reading has suggested a capacitor connected across the DC output of the bridge rectifier for smoothing out the AC ripple. Is this correct, and if so, what size capacitor would be required?

Any advice will be greatly appreciated !!!

Thanks,
