Think the general idea is to keep it watered once a week and put in indirect light, until new stems grow out. I'm not sure what those white "beards" are on your orchid though. Will wait for someone more knowledgeable.
Hard to tell from your pics but I'd suggest you re pot into a decent plastic pot which has drainage holes in the base. A thorough watering when the compost is dry and then let it drain before putting back in an "outer" pot. Bright light rather than sun - you can keep it outside if you have a suitable spot for most of the summer but bring in before danger of frost. The bit hanging down on the RH side is a new plant which you can detach ( keeping the aerial roots ...white bits ) and pot on.
No, no trimming, those stems contain the plants food reserves, it looks way way to wet and the white on the bark is possibly a salt build up from fertilisers and watering.
I would re-pot it in new orchid compost in a pot with good drainage and keep it on a saucer rather than inside a fancy pot. I suspect you will find most of the roots have rotted from being to wet so it will take the plant a while to start growing again, be careful not to over water it in the meantime.
If it were mine I would also cut off the little baby plant and put it into the new pot as well. water by immersing the entire pot in a tub of luke warm water for 5 minutes once a week (LESS often in winter)and allow to drain completely before putting it on a saucer or into an outer pot. If the bark is still wet like it is in the picture when you go to water, don't water let the bark dry completely before watering again.
