Yosemite Park?

Me and my dad are going to Yosemite for the 4th of July. We are staying at the Curry Village, and we want to go biking and hiking. We want to know if we could go fishing for trout for dinner, and if there is anywhere we can cook it. We have gone deep-sea fishing, but we do not have our own fishing poles, so is there anywhere we could rent one. Also, since we are using a bike rack to take our bikes there, I wanted to know were I could put our bikes at night.
