How to get rid of some of the other on my iPhone 4s?

I have a 16GB iPhone 4s, 6.81 GB is taken up by other, and it is just so frustrating to me. I know that it needs to take up some GB, but having almost 7 GB of it taken by just the other is ridiculous. I have cleared the cookies and history on the safari. I've deleted my messages. I've gotten rid of unneeded contacts. I have cleared up my email. I don't know what else I can possibly do. Can someone please tell me how to fix this?

Why is my iPhone's left speaker (for sound) not working?

I had recently damaged my phone by dropping it on pavement (approximately 3 feet), and it slid about 20 feet. Just today, I noticed the the left speaker on the bottom of the phone is not working. I have a feeling that it's not working because of the impact of the phone falling (I had a snap-on case at the time).Is there any way for it to get fixed without replacing the whole phone? And are there any good websites for parts? -Thanks
