Always eq your mix after production, if you mean eq the whole track on the master channel, or else you'll eq the instruments and stuff different than you would if you had a clean master.
If you regret the eq'ing or want to change it, it will be harder to make it sound good i guess...
I usually EQ after the composition and arrangement are done with. That's just me though, I see nothing wrong at all with EQing while you're composing and arranging. I just don't want anything to distract me while I'm working on the musical side of things.
I EQ every new sound i add instantly, if its necessary, basicly, i EQ them after i add them or when i see its needed.
Same. How do you know for sure if you can make it sit in with the mix right later?
EQing is part of the musical side of things.. EQing = creating sound, creating music. Arranging notes isn't any more musical than eqing and compressing to create a sound IMHO.
You can EQ during or after all the parts of the mix have been recorded. There are no rules.
But, for me it's easier to record all the parts first while I still have the inspiration and make the tracks fit without too much processing. After I'm done with recording and an approximate arrangement, then I'll start mixing.
Again, there are no rules and you can do whatever works for you. The only reasoning you might want to consider the above suggestion is that this way you might stay creative and not get bored with your own ideas.
