Leej, you should know better than to leave such an opening on a thread title. "Looking For Some Songs" could get a whole plethora of songs since you mention no titles. BUT...since I'm a super nice guy I won't do that. Here is what I think you are looking for for the first part of your #3 request. Copied and pasted from Cowpie.

500 Miles Away From Home

       D7            C              G
  I'm five hundred miles away from home
  G
  Teardrops fell on mama's note,
                             Em   
  when I read the things she wrote
              D7                C                 D7
  She said "We miss you son, we love you, come on home"
         G                                             Em
  Well I didn't have to pack, I had it all right on my back
          D7            C              G
  Now I'm five hundred miles away from home
  
  Chorus:
   G
  Away from home, away from home
                          Em
  Cold and tired and all alone
           D7           C              G
  Yes I'm five hundred miles away from home
  
  (Spoken) I know this is the same coat
  I took when I left home
  But it sure looks different now
  And I guess I look different too
  But time changes everything
  I wonder what they'll say,
  When they see their boy lookin' this way
  (Sung) Oh, I wonder what they'll say when I get home
  
  (Change to key of D - D,A7,G,Bm)
  
  Can't remember when I ate, it's just thumb and walk and wait
  And I'm still five hundred miles away from home
  If my love had been just right, I'd be with them all 
tonight  But I'm still five hundred miles away from home
          
  Repeat chorus (In Key of G)
  
  Oh, I'm still five hundred miles away from home
