I want to download and add Lua's string api to the mod. I know how to add the api, but I don't know where to download the api. Anyone know?

Lua's string API is built in… Just use it like you would normally.

If you mean the default lua string library, it's already included. Otherwise, we need to know what api you want.

But string.gsub and string.find don't work.

Seems an error in your code. I can't tell without the code, but I think the problem is that you defined a variable called string. If that's the case, just rename that variable and it should work. But again, I need to see the code to be sure.

Don't worry, I've fixed it (I think). On another note, when a message is sent to a turtle, it outputs the sender ID on line 1, the message on line 2 and the distance from the sender on line 3. If I wrote local msg = rednet.receive(), how would I access the message part?

Like you said, rednet.receive() returns three values: the id of the sender, the message and the distance from the sender. You just have to store the values you want in variables, like this:
local id, msg, distance = rednet.receive()
local _, msg = rednet.receive()
local id, msg = rednet.receive()
