shift linkage ?'s

[Festively Jolly]

Ahoy Hoy!  ive been noticing some serious wear on my linkage and
whatever else that entales :)  the throw is REALLY notchy and im
starting to grind the gears every so often because the shifter will go
about halfway into the gear and then stop. its like there is an
inbetween gear.  and just by hait when the shifter stops i engage the
clutch and it grinds :( MY fault completely but its just annoying.  
  the car is a 1988 Audi 90 FWD and it has 121,000 miles on it with all
original components.  do i need new bushings or something? i have NO
idea.  also, how would i reduce the throw?  i think i heard some people
talking about them a while ago, but i cant remember. any kits or DIYS
jobs?  well thank you much!
