And to answer your question - everything you buy in shop carries over aside of the temporary stuff like cash and time skip obviously.
Every girl has 10 'levels' first 5 girls give 1 energy for 1st 9 lvls and 20 diamonds on last level.
The rest of the girls seem to give 1 diamond for level 1 and not sure about anything past that.
