A simple reason to have your sytem either engineered for your room and calibrated properly for your setup is that it will make your system sound tremendously better!
You have so many varriables in such a small acoustically challenged space, that working with someone can yeild a tremndous(perhaps 3 fold or better) sonic(and visual) improvment! It would be akin to having WolfGang puck drop off all the great ingredients to a dish, and not leaving the dirrections!...and thus you make the dish with less than par results..even though it may seem tasty to you..it can can taste sooooooo much better!...it's a choice.
You do have the advantage of a diffuse soundfield will adresssing reflectio npoints in the room with the books/shelves. Your immaging and soundield will be better than most if you have books all over the place(would have to see your setup). Still, there are many many other variables, like bass response, volume for each speaker, proper crossover selction, phase, soundstage width, cohession between speakers, proper possitioning of speaker/seats, Speaker toe-in, perspective and height/placment of speakers, etc, etc.
Anyway, there are lots of ways to do it all so very very wront and compromised for optimal results. If you've never heard it done correctly, you might never know what you're missing, or what you could have with some edjucated consulting.
