I don't know how many miles your 4/4 has done. After 75,000 or so, I found my car's clutch increasingly difficult, and like you, I ran out of adjustment.
At 90,000 I even shortened the cable, and not long after that the cable snapped; luckily while I was parked.
I bit the bullet, and had the clutch replaced, along with the throwout bearing. The bearing was completely shot!
This made such a difference, and I could again select first gear while stationary!
I'd recommend have your throwout bearing checked, with a view to replacement. This may fix your car's ills.
