I use pedals with my X45 so dunno about rocker question - use it for aileron trim which it works very well for me. But my guess to this is yes.
I use Win98 for games (XP dual boot for work & other stuff) so dunno about Win2k questions, just know you can't use rotors with win2000/xp. think the rest works well.
The center spring doesn't wear out for me. I have the hat and trigger go in about 6 months. I get around this by buying stick at CompUSA with in store replacement warranty for another $10. Then in six months go switch it out for new X45, lay down another $10 for another replacement policy, in 6 months - repeat process.
try it, take it back if not happy - but it ain't gonna last anywhere near 5000 hrs ( 2 hrs a day = 2500/365 = almost 7 YEARS - ahhh .. nope
