I want to replace the button with a no/nc/c one. what do green/blue wires denote? any specific type button i need?

The color of the wires in this case is of no significance. The button serves to apply continuity between the two wires. When pressing the button, it is like touching the two wires together which activates or stops the device. When replacing the button you will want to use one that acts as a momentary switch (connects the two wires only while button is depressed). Hope this helps.

How many seconds of recording does this hold average.....more that 120 seconds??

It will depend on things like the sampling rate of your recording. At a low sampling rate (you really don't need higher quality, given the speaker) you could probably fit as many as 6-8 average songs. At higher quality sampling rates, maybe only 2.

How do I get rid of previous recording? I delete and replace but it still plays one after the other.

I had to not only delete the old recording but then empty the trash can of the computer. It seems deleting doesn't actually delete it but just marks the space as open for rewriting new data.

I connect the board to my computer, note a green light, and push the button. No sound. Unit is 'on'. Whats up?

Here's what's up: The micro USB port kicks the board into storage mode, meaning when it's plugged in via micro usb it only functions as a storage device. So in order to use the device you'll need to wire it to a 5v power source, or a 3.7v rechargeable battery. The seller states the micro USB port does charge the 3.7v battery, so no need for a break away connection.
