No problem. Baby steps. Can seem overwhelming at times. Base layer is critical. Get your bed leveled. Print a couple skirts and manually dial (http://www.thingiverse.com/thing:915845) in your bed to make sure the skirt lines are even and printing well. Slow down to start. You can slowly up the speed until something breaks, later.
Base not sticking? My fav is cheap dollar store picture frame glass (or mirrors but make sure it's glass) on 0.5mm thermal pads (sticky but not adhesive) and a few light coats of Aquanet hairspray.
Layers crack/split easily? Up the temp. Possible lower the fan speed.
Hairy prints? Lower the temp.
Try to keep a few notes as you go. Change only one or two settings at a time.
