Help!!

I know this probably sounds very lame but I have no idea where to start as I embark on this project. I searched for the word “beginner” in the forum but even what that turned up was a little too advanced for me. Please can anyone help me with at least a starting place to go from? All I’d like to start with is an amp to take a headphone output and power a pair of cheap speakers (Specs below).
Any help would be much appreciated.
Many Thanks.

Long Term Power 50w
Short Term Power 90w
Frequency Range 84Hz – 20 KHz
Impedance ohms

Project 3a from Rod Elliott is a good amp. He also has an new MOSFET amp that would work well.

I trust that gainclone is the perfect project for very ambitious beginer. it has very low parts, cheap, and the chip is idiot-proof meaning: it takes a nuclear wrhead to destroy it.
Go to national semiconductor and download application notes on LM3875, most of everything you need you can find it there.
