Do I have bad luck with springs or what!?

I dunno... it is hard to quantify but as everyone said, get multiples. Maybe I should get two of everything! Cheap insurance.

That insurance policy is only in effect as long as you are absolutely positive of the storage location. Forget that and the policy goes right out the window! 
Ask me how I know.

When my TRS broke after 1k rounds and 5k dry fires, I was told to lube the spring and keep it wet. I did that with the replacement CGW LP TRS, and so far,  so good.

Interesting. Did Cajun tell you that? Maybe a dab of grease on the TRS will help?

You are correct! Well since I replaced the firing pin, FP spring, hammer spring, FR block spring, and now have an extra TRS, all of these extra springs and the nice punches I bought to do the job, are inside my CZ 75B case.

Now as long as I don't lose the case!

With all the springs and tools on hand,  you'll won't need another spring for 30K pulls or more.  It's a CZ rule of thumb.

Did you say you had an extra Slide Release/Stop?   

[rifmon]

no?!?!

and while I'm at it should I get an extra recoil spring? I like where my brass lands so the lb is fine

Recoil spring will last just fine.  If it weakens,  it tells you by throwing the brass farther--no biggy.

I've broken two or three slide stops over the years.  I strongly recommend you have a spare.  The first time I "borrowed" another CZ shooter's slide stop to finish a match.  I was lucky. 
I recently broke one and had my spare on hand and just kept shooting.  I promptly ordered and recieved my new "spare".
I also take two CZ 75s with me to matches.   Belt AND suspenders.

1SOW, is this a Cajun part or a factory part?

[1SOW]

I buy mine from CZC.  Their's has the nub that contacts some 147 bullets  rounded off---maybe they all are now??--- and feeds smoothly.
