Help needed for a Phal that seems like its about to bloom (pics included)

[nutmeg_trippin']

Hi everyone
My Phal has entered something like a 'dormant' state for quite some time after it shed it's flowers (see that post: http://www.orchidboard.com/community...-included.html)
Finally, new flower shoots are growing back after almost half a year of no changes.
I water the plant with low-chlorine water once a week, and use no fertilizer. Here is a pictures of the new shoots:



And here is in overall pic of the plant, with the new shoots highlighted:



Do you guys think I should start fertilizing it (I have instructions)? I am still wondering why the flowers that the plant had in the beginning fell (check my old post, link at top^). I just hope this time, they last longer!
Also, should I just leave the plant like that or should I trim the parts of the stem that are above the new flower spikes that are forming?

I'd appreciate any help, thanks in advance!
