Just keep brewing.
After you brew more, refine your techniques, eventually move to the same process that commercial breweries use (that means going all grain) and get 20+ batches under your belts, those issues will go away.
I don't remember the last time I tasted that "homebrew" taste...except maybe a recent swap.
And remember...some styles are supposed to have some lingering yeast sweetness...like a good wit.
