Join KVR, and ask in the 'getting started' forum. You'l receive a world of help as long as you don't used pirated software. Fortunately, there's a world of free software that'll both help you record, accompany and master your tracks.
Try Reaper or Mu.Lab for free software recording solutions [Reaper is effectively shareware, and if you want to pay it's really well priced and as good as Cubase or Logic.]
Add Crystal, Automat and other great free synths to add extra spice
Add Sampletank free and some free drums
Master it using the free effects that exist, many as good as payware.
You'll nee a way of piping the MicroKorg into the computer - choose an inexpensive USB audio interface with a guitar Hi-Z input, and you could even then use some of the great free guitar amp sims to add guitar back into your finished tracks.
As for tutorials, head over to the soundonsound.com website. Search for the synthesis tutorials, and also read the monthly column on Reaper if that's what you use. Finally, there's some excellent tutorials on mixing and mastering - and all for free.
