I personally don't play any other bemani game, but I just tend to keep playing songs when I hit a wall. Keep playing songs you fail, as well as playing songs you can pass.

I've found if you have trouble with certain chords that playing easier songs on random or s-random helps for practice.

Just keep playing and it'll click. I'll leave the better details to be covered by the more experienced players here. :P

This.
I can say the switching between IIDX and Pop'n works.
Never touched Pop'n before, but since I played IIDX I was able to do some stuff a bit...although figuring out where to hit the notes was the hardest part for me.
Switched back and forth between IIDX and Pop'n...I was passing some 37-40 in four months and never played it before.

Of course I'm also a sinner and use Beat-pop. :x

1 game of Pop'n is around US$1.75 and IIDX with e-amuse is US$2.75 per game.

Holy god. So expensive. I cringed at paying even near 200 yen a game when I lived in Japan. >_>
I was a tight wad and hunted for 100 yen cabs.
I seriously commend you for paying that much, that takes some dedication.
