Help choosing between iphone 4s, 5c, 5s?

I currently have the iphone 4s. I think the 5c and 5s look really cool though. I was thinking about getting one of the two, but I had a few questions.

1. What is the difference between the 4s, and the 5c and 5s?
2. What's the difference between the 5c and 5s?
3.Is it worth it upgrading models? Or is the phone I have pretty much the same as the new ones.

IPhone 5 forgot password (with iOS 7)?

Yes, this is very stupid as we all know. Some info about my iPhone 5:
-Never hacked or jailbroken
-Bought in June 2013

Today my friends tried to break into my iPhone and eventually they figured it out after a few hints from me. Once they left, I decided to change my passcode. I locked my phone and then an hour later tried to unlock it, but no luck! It has been disabled for up to an hour (iOS 7 doesn't show amount of time remaining when disabled) but it went back to disabling for only 1 minute and I have had many tries to get the passcode.

After looking online for a while, I found that restoring the iPhone should do the trick. I plugged the phone into my computer but it says that in order to restore, I need to "Turn off Find My iPhone; go to iCloud settings on your iPhone and turn off Find My iPhone before restoring" but I can't get into my phone.

If you're still reading this (and I greatly appreciate the fact that you still are), do you have any ideas to fix this? I need my phone for school tomorrow and my parents are not very happy. And since it is a Sunday night, I don't think my Verizon retailer and/or Apple retailer are still open. Any tips?

What's the best website that will unlock an iPhone?

I'm thinking of buying an iPhone from eBay, but I'd like to unlock it. So what is a good website that you've used to unlock an iPhone? The service on the iPhones I'm considering are either Sprint, Verizon, or AT&T.

How to transfer a large amount of photos off of my iphone and onto my computer?

I have 9300 pictures exactly on my iphone and It won't let me sinc the photos or download them to iphoto on my computer because I have too many, they take up all the memory. I really don't want to loose them and I have no idea how to get them off. I don't use Icloud, should I or is there something else I should try because it takes to long to send them individually
