So far, I have been playing around with Virtual DJ. I want to DIY a controller using a microcontroller. I know that on some controllers, there's a display with the current song's position and name on a deck. Is this data transmitted via MIDI or would I have to write a plugin?

As far as I know, there's the possibility to send the MIDI Timecode through a (USB-)MIDI port. So, if you're planning to make a DIY controller, expect to decode this kind of message (I think it's a Song Position MIDI message).
As for the name and deck number, I don't know. Read the Wiki and search for these info by yourself.

Pretty much all data can be sent via MIDI or HID protocols.

LED's or display symbols that are on/off are typically controlled by the software sending MIDI note on/off messages.
Value fields such as track number, time (Mins, seconds, frames), etc. are sent as MIDI CC (Control Change) messages, which can have a value between 0 and 128.
For text displays, each character is sent as a CC (For 128 bit ASCII) or two CC's (14-bit LSB/MSB) for 256 bit extended.

2 things (didn't want to start a new thread). Is there any way to do a static and active waveform display? Also, is it possible to map sliders to different loop lengths, where a movement 1/6th of the slider could change from 1 beat to 2 or 1/3 move from 1 to 4? Additionally, can I pulse an LED to the beat, like the SYNC buttion?

You can control loop length and you can pulse an LED to the beat.
Waveforms would be very difficult to accompish, especially via MIDI. I think you'd be looking at plugin territory for this and even then it would prove difficult.
