I would get a few things right before progressing to guiding, as you said, one
thing at a time.
Get routinely good polar alignment, essential whether guiding or not.
I strongly suggest the DARV method of polar alignment as being easy to
understand and execute. Google DARV for tutorial, it's easier and quicker
than traditional drift alignment. There are other methods once you start
using software when imaging, but until then DARV is brilliant.
Get a cheap intervalometer on ebay so you can leave the rig to do its
thing when taking lots of subs. Get your imaging routine down pat,
including using darks, flats, etc: ; learn sub stacking in DSS or other
stacking software, and basic image processing. When happy with all that,
move onto guiding. Once proficient at guiding, you can then decide whether to stay with a DSLR, or move on to a One Shot Colour camera, or a mono
CCD camera.
