I'd go higher on the bridge rectifier... 15A 100v, part # 687-5642 @£1.75
This will need to be mounted on a 5degC/W heatsink or better (or the aluminium case you mount it all in if its at least 200mm x 150mm)

Also its 25 * 1.414 - 1.1 (forward drop of diode) = 34v, which might be a tad hi for a 30V driver.... 8% regulation its going to be nearer 37v off load... just need to check max driver voltage.

10000uF capacitor will give 2% ripple @ 6A which is more than adequate, for 3% ripple you could go as low as 6,800uF (381-9093) @ £8.59

Dont forget fuse holder (384-011, £1.23) and slo-blo fuse @ 1.5A, crimp terminals for the fuse holder and bridge rectifier, ring terminals for the capacitor, 10A-rated 'chocolate blocks' for input and output
