Do you guys think it is more important to get the monitors before getting the hardware/software.
Of course!!!
Reference Monitors will help you hearing exactly what you are producing in the Pc/Mac. Any monitor will not do because they modify "colour" the frecuencies( f.e. because of the construction). That way you will not be able to Listen/equalize precisely the sounds you are recording. If you are not aware of what this means, you should learn about it! you will not regret!!
About hard/software I think exactly as you do but I am getting surprised day after day so keep your mind open... Of course HArdware sounds different... And analog hardware sounds thick and dense, just fat!!! But talking of analog stuff, it is expensive and not so easy to control like software and you will not be able to store your sounds like you can on a digital synth, or an analog emulating, analog digytal hybrid, or on the software...keep that in mind!
I addition to that I want to say two more things:
Maybe you are not even looking for the Analog sound, there are sounds that are just done Digitally(and the way around) I saw you make trance, so there will still be a strong digital influence in many of your sounds!
The other thing is that good Software syths are surprisingly nice sounding, and with the right equipment( hard and/or software) you can get really excelent results, so its finally up to you and how you deal with your stuff!!!
Finally and returning to the thread´s theme

I think it is all said...
Mastering HArdware is expensive and software can surely spare you some money...
If you want to make it pro you will need a multiband compressor, and yes, they are expensive!!
If you dont care that much, get a good compressor, a drawmer for example, and go along with that
