It seems that everybody has different ideas of how to treat orchids. All I can tell you is what has worked for me, and we have about a dozen which are now flowering for a second year. This is phalaenopsis type.
I use tepid tap water and plunge the pot in to the water for about 10 minutes approximately every 7 to 10 days. If the 'roots' are bright and fleshy it doesn't need watering, if they start to look soft they need watering.
During the summer months I stood them all outside in a bright car port and mist sprayed straight from the garden hose once a week or so.
I experimented with cutting the flower shoot right back and to within a couple of nodes of the bottom. It didn't really make any noticable difference to the way it threw out the new stems. Do be careful with the new stems as they can be quite brittle and the tip is very easy to knock off as I discovered . Good news it that it has since flowered again.
As they are only in their second year I've not had cause to consider repotting yet.
