This question cannot be answered fully without knowing if the basement is below the grade of the building's sewer run as the installation may involve the use of a sump system. The actual installation is not all that difficult, especially if you are handy with a few tools.
no

Sorry but the original question can not be answered here, as you need to understand plumbing codes and in the end you must follow local codes. Same as this question, how to plumbing kitchen. There is too much involved to explain the process. I would suggest getting a book on plumbing to accomplish this task.
In plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture.
I'm not a professional plumber, but fairly experienced with plumbing. From what I understand, a p-trap allows for a small pool of water that acts as a barrier between the nasty stuff down your drain, ie. poisonous gases and smells. It also can catch bigger stuff that shouldn't be going down the drain and block it in a generally easily accessible spot, versus clogging up further down the line. It is certainly required by plumbing codes and should the sewer/septic gases build up they can cause illness/death or cause an explosion.
What is the minimum distance between the bottom of a sink and the trap attachment for a bathroom sink
You have to take the floor apart and reduce the piping to 2". You also have to install a p-trap as there are NEVER p-traps under toilets. All p-traps are BUILT into toilets!!!
A Vented Running trap with two clean outs or a P trap.
Invest in a plumbing how-to book. Info is invaluable. Plumbing codes may be a problem, they differ with locale. Normally the waste is no less then 2" and 30" high and is piped into a 2" P trap IF your piping it into a kitchen sink provided the waste is 2" them some codes do allow a direct hook up if the discharge tee is at least 3/4" diameter
