old threaded headset...
Just unscrew the nut with a wrench and all the headset bits should fall right out except for the headset cups which are pressed into the frame. To remove them, you've got 3 choices: 1) take the frame to the LBS and have the wrench get em out, 2) buy yourself a Park headset cup remover for $30 and do it yourself or 3) use a hammer and long stemmed flathead screwdriver and slowly tap out the cups being careful not to get one side out further to avoid ovalizing the headtube.
Personnally, I was in the same boat as you: newbie rider who wanted to overhaul his bike and I did it all with simple tools my pops had. Since then it's been 14 years and several bike tools later and I no longer take my bike to the LBS to get work done. # 3 works well, just go slowly.
