The SOL emergency bivvys are super cheap and pack tiny/light but not breathable... some of the lightweight pertex bags are only 70-80g heavier but a lot more breathable.
Electronics wise - got two SP dyno hubs (rebranded as Exposure) and they've been flawless, heard nothing but good things about SON too. Exposure Revo is a great light for the size/weight, plug in taillight is good too. Handy to be able to unplug light and remove it from the bike, the standlight doubles up as a torch pretty well when you do stop rather than using juice from a helmet mounted light if you use one...
