Some of the things above you can make as your skill grows. Like 123 block, sine bar, collet blocks. It really comes down to what do you want to do. Square, ruler, cutters, mic., caliber, DTI, file, scribe, parallels. all pretty much must have for accurate work. But by far the best thing recommended was safety glasses.
I recommend you watch some basic machine shop safety videos, MIT does one, Mr. pete2222 I believe has some. But please be safe even that small machine can hurt you bad and fast. One more thing the charts mentioned above are all on line.
