Of course, I didn't have the best writing when I first started practicing the kanas - for someone who's never done it before, who would? Just keep writing it over and over, and your muscle memory will begin to kick in as you go. Don't worry, practice is what makes improvement.
As far as sounds for the kanas, just do a quick search on a Search Engine for words like "hiragana" "chart" "sound" "play" "listen" etc. you'll be suprised what it comes up with.
