is this a good choice for moderate hp gains ?

i am just getting into the car performance seen so i dont know a whole lot about it . this is what i was thinking of getting for my civic lx . iceman cold air intake , headers not sure which brand probably either 5zigen or dc . cat back exaust not sure which brand but i am thinking 5zigen . how much horse power can i should i gain from these parts . i would be happy if i could get an extra 20 hp out of these . in the future i was thinking of also adding a supercharger . would i have to do anything to the stock engine to support the supercharger or can i just install it . also if anyone gan give me ideas of how to get from 108 hp to 150 hp the cheapest route besides nitrous that would be really cool . thanks alot .
