GTA IV expansions question

What GTA IV expansion missions collide with the original game? I heard that Ladies Half Price, Diamonds in the Rough, and Diamond's Are A Girl's Best Friend collide, but I'm not sure, as I haven't reached DitR and LHP. So if you can list all the Lost and Damned and Ballad of Gay Tony missions that collide with the original GTA IV, it would be REALLY, REALLY, appreciated.

i wont spoil it :)

No need for a mission description, just when missions collide. I completed GTA IV...

Not necessarily collide, but you know the mission where you all of a sudden have to save Roman from the Russian loansharks in the warehouse on Bohan? You get to see a side of that mission that you don't see in GTAIV. Same with the mission where you had to kidnap the Ancelotti's daughter, Gracie, for the McReary family.
