Well, you kinda' forgot the most obvious one, which is balance.
The other ones are all fine, and mostly situational. Reverb only becomes important in situations that call for it; if you don't already have natural ambience, or if you don't have any room mic tracks to play with, etc. Or if it's something that a particular track (or several tracks) needs.
EQ can range anywhere from somewhat to very important, depending on how well everything was tracked.
Bla bla bla bla bla. It's all important, really. Whatever effect or process you happen to be employing ... is important. And yet, at the same time, none of it is really important. What matters is that, in the end, you have a finished product that sounds great.
Whatever methods you use to arrive at that result are the correct and important ones.
