Thank you all who offered advice. I got done work today and decided to tackle the zerks. 
The drivers side upper lift arm wouldn't take grease so I pulled the zerk, there is an elbow on the end that the zerk screws into so I took that out too, it was caked full of what looked like putty...lol anyway, some break clean and a pick and I put it all back together and it took grease! YEAH
The passenger side wouldn't take grease the other day but I started the tractor and moved the loader up and down then shut it down and then released the pressure on the lever, it took grease! Yeah
Then I moved on to the upper bucket pins, both zerks were broken off, I tried some left handed drill bits thinking maybe they would thread the remains out, no luck so I drilled them out to 7/32.nds and used my 4 way tool to re thread them and installed new zerks, boom done!
Now the lower bucket pins, neither one would take grease, I removed the zerks,cleaned them with the pick and in the hole and sprayed everything out with break clean and put them back in and they too took grease! I'm 100% greased now
Then I moved on to the hydraulic hoses I added and used two pipe wrenches to tighten up the fittings, I did get some more on them, I hope this cures them from seeping.
I think my next adventure will be to change the oil, filter and fuel and hydraulic filters too. I put a new air filter in when I got it as the guy gave me a brand new one in the box.
So thanks again
p.s. that oiler tool probably would have worked for the two lower ones. I may look into getting one of them.
