1022 is deffo heading in the right direction
-Too low to be a starting gravity (shoud be around 1040 or above) and too high to be finished yet (should be below 1014 ish)
Sounds all is well
Re samples, If you have a tap on the fermentor just take 100ml out into a hydrometer jar for samples. Get rid of it after testing (drink it!) that way you learn what it should taste like, get a reading, and theres no fear of contaminating anything. This way no need to steralise the jar or hydrometer, just wash after use.
