Please read through that site, it has all of the answers to the 
questions you've been asking so far about licensing/royalties. Yes, you 
will have to pay royalties if you write and include your own MP3 decoder 
(a hell of a lot more too).


2. I'm positive that the file format it is out there on google 
somewhere. 4 years ago in my ASIC design class, my team and I wrote VHDL 
code to create a hardware MP3 player and we found the specs very easily. 
Find the file specifications, then write your own MP3 file decoder to 
send chunks of audio data to OpenAL buffers. Or, find the appropriate 
libraries for whatever system(s) you wish to use it on and include those 
headers.

On Linux, it looks like my mp3 decoder header files are in 
/usr/include/mpeg3*.h
