When I played through Pearl, I felt obligated to plant berries everywhere, thanks to the stupid Berry checker. I have like 200 of each EV-resetting berry, so I just use those if I'm not sure what EVs my Pokemon have.
http://www.serebii.net/games/iv-calcdp.shtml is a nice IV checker and stat calculator. It calculates both ways - you can plug in the IVs and EVs you think your Pokemon have, and calculate the stats at different levels to make sure you trained them correctly.
