As far as conflicts go, I think the "Bank" mainly. I have the Points bank enabled and I'm afraid your bank will conflict. I will probably have to choose one over the other (yours appears to have more features that I've been looking for). But, if I drop the points Bank and use yours I don't know what capabilities I'll lose in the process. For example, Points Bank does not count the points in the bank to count on the Leaderboard (which I want), does your Bank do the same?
If I drop Points all together then I'll probably lose the ability to award points for a lot of content that your app doesn't cover (I have a list).
Also, in Points I can RENAME "Points" to anything I want (in my situation I renamed them to "Wing Nuts"). I don't think I can do that with Members Shop?
