The bays are probably just suffering from a bit of cold and change of environment. I'd simply snip off any damaged leaves.
Cut all the raggy bits back on the buddliea. To be honest - it doesn't need to be in a pot that size either. That won't help it establish - it's a tiny plant. It'll discard some foliage as it tries to make roots. They like free draining soil, so don't overwater - even in a pot. Make sure it's up off the ground for drainage.
Can't help you with the blackcurrant, but if you've got water on the foliage during sunny spells, that can cause a bit of superficial damage. Always water plants at the base, especially when it's sunny - don't spray the foliage. They're pretty tough, so it's unlikely to be anything serious
