Not neccesarily, equalized mod packs are great when it comes to ratios, like a modded part will have the same fuel intake, but more thrust and more weight.
Foamy: tellmetellmeTELLMETELLMETELLLME!! Fine, if you REALLY want to know...

Well once one arm turns to the side, it starts to thrust force horizontally, accelerating the craft, making the other arms eventually go with it. Thats why you can use the command pod to spin it the other way, and it will stay like that.
Whoa whoa whoa, why didn't you shoot the sattelites at a 90 degree angle? I mean I doubt the boosters would go straight but that would be a cool way to get payloads efficiently into orbit. As long as it works xD
Err-uh... if people can't manage to use stock parts and use decouplers, I'm pretty sure they won't be interested in the game and/or comepletely fail at flying a rocket. And what do you mean by trial software? Stock parts? People shouldn't even bother use mods just because they can't get a stock part-made rocket into orbit...
