Taking care of an orchid plant

Last September we were gifted with a phalaenopsis orchid plant, whose blooms lasted a long time, maybe two months or so. Once they fell off, I repotted it - soon there was a little shoot growing off the stalk that sprouted buds and it bloomed again this June!

Here are some pictures:

I recently found an excellent video on how to take care of these orchids - a must read for anyone who has been gifted with an orchid plant! It answered ALL my questions -
why were the leaves turning yellow?
should I move it to a bigger pot?
how often should I water?
what do I do once the blooms fall off?
Why is the stalk drying up?

I cannot recommend the video enough. I have acted on its advice, cut off the dried up roots and the stalk, repotted into a slightly bigger pot. Now I am going to sit tight and wait for the two small leaves (and the two tiny ones that are just sprouting) to grow as the root system adjusts to the new environment.
