Hi!
There aren't really any set rules. Go with what works. Adding gear is always an option and nobody as far as I know buys just because they have to or it's "mandatory" to do so.

Getting an additional synth workstation KB or a module isn't really a must at this point. If the Micro Korg works and does the sounds that you find expressive enough for the task there is absolutely no need to add any other synth. Again, no harm in adding one either since you will basically add more sounds to your palette. Whatever other bands do is not at all important. What they do works for them and what you do works for you.

Speakers and mixers are pretty much a must have for most KB players since thats kind of what KB players use. Kind of like guitarists and basists using their amps.

Whether you decide to use a KB Amp or some speakers is entirely up to you. Pick whatever goes with the sound of your band. You can always change and upgrade. It's never a final decision.

I must've gone through a dozen of different speakers until I finally stopped and decided to use Tannoy System 600A. Price isn't cheap. But the sound is exactly my kind of sound. even with only two connected it sounds like you're surrounded by the mix. Perfect for mastering and mixing. I went through ROlands, Yamhs (had to put pillows in front of those 'cause the sound was really hard. ) and finally ended up getting into higher end stuff like the Mackie, Genelec. hated all of that stuff.
Tannoy System 800 were alright. Then I discovered that the cheaper version 600A was exactly what I was after.

Mind you I wouldn't advise to take the 600A to gigs. even though an entry model it's not a cheap pair. $1250.00 nowadays. Don't want one of your buddies knocking them over by accident or else.

BTW have you checked for that post by AJ?
