As tanza has stated. the pups ears are not a worry, about 12 weeks they should start to settle down, when they have a full set of needles for teeth. And speaking about needles, keep them quarantined, (eg no dog parks, very local walks, etc), so that his mother's immunisations would still be effective through her milk. I await until their adult shots before releasing pups, then I know that they have at least the best start in life.
Another item, buy a Dremel rotary tool, and start grinding their nails. The earlier you do it, then they get used to being trimmed, and the noise. A little bit at first, do not get down to the quick. It is done with the fine emery paper one, try on your own. It can get hot, NOT RECOMMENDED, so go to another nail if it is getting to warm.
Keep learning and asking questions - no question is too silly or too hard, but you should not be asking the same question repeatedly. Have fun with your new found friend, and treat her like one of your human kids, about 2 - 4 yo. Best of luck.
