How does the cell regulate different metabolic pathways?
I heard somewhere that cells ………………………… so they regulate where they use up the energy.


Yes NADP/H is primarily employed in anabolic pathways such as fatty acid synthesis, while NAD/H is employed in catabolic pathways such as glycolysis.

I don't think there is a general rule for other "energy-currency" molecules (pyrimidine triphosphates are not used except in some rare cases such as glycogenesis).


  I mean is there a simple map which contains the main processes and the energy carrier and regulatory compounds?


You can search for the term "metabolic network". It would be too huge so it is better to look at specific sub-networks. KEGG is a good site for finding metabolic networks. There are other representations like hive plots, to visualize very huge graphs.
