Can I put a Straight Talk of Tracfone sim card into an iPhone?

Currently I have an LG 800G through Tracfone. I want to buy an iPhone 4S or 5 off of Amazon or Ebay as an upgrade. I want to stay on Tracfone, but I could switch to Straight Talk if I had to. I have a lot of questions. Could you please answer as many as you can?

Can I put a sim card into an iPhone?
Does the iPhone that I buy have to be through a specific carrier?
Does the phone have to be unlocked for me to do this?
Do I have to buy the $45 Straight Talk plan? After, can I buy the $30 plan?
If I can stay with Tracfone, do I have to buy a specific amount of minutes?
Will I be able to get data, texts, calls, apps, etc. When I switch?

Sorry that this is very long. I really need to know because I want to do this for my birthday, which is in a few months. Please answer as many questions as you can, but I will appreciate it if you can answer them all.

What can use to seal in sharpie on plastic?

I bought a plain white iPhone case off of amazon.com and I also bought some colorful sharpies. I made a cool tribal pattern with the different colored sharpies… I know so cool! Lol anyway it turned out really well and I like it but I noticed that throughout the day it has been fading (and in some spots completely gone) where I hold it. I want the color to last longer because it took me a Lon time to do and I like the way it looks.

Is there anything that I can put over the color so that the color stays? I considered clear nail polish but i don't know if that will help/stay.

Did i wait to long to put my iphone in rice?

I dropped my iphone in a bathtub full of water. I quickly grabbed it (it was only in there for a couple seconds) and dried it off with a towel before turning it off and everything seemed to work fine except for the volume buttons. I turned my phone off then on again and still everything worked except for the volume buttons. I struggled opening a bag of rice but after about 2-4 minutes of struggle i finally got it open and put my phone in it, closed it and put it in a cupboard. Think i waited to long? Think my iphone will survive?
