If it was just a leak problem, I would go for 3).  But, the "thick red goo" 
and apparently since the plane has been not flown for 10 years (or have I 
mis-understood?), the canard should come off as part of a good inspection 
and to allow access to the hydraulics and the broken/missing link (of your 
other post). What I would do is:
1) remove canard
2) add some fluid to reservoir and run the pump and cycle the gear cylinders 
until you locate the leak.
3) remove pump and reservoir, clean and repair as necesary,
4) maybe flush all the hydrualic lines... this would be a pain-in-the-ass do 
do but the red goo might be throughout the system.  On the other hand, the 
red goo may not be a significant issue (?).
5) fix the link rod.
