Q1: Each speaker is a channel. Left and right. 2 channels for the tweeters, 2 channels for the mid range, 2 channels for the mid bass, and the last channel you will have is sub. When you bridge an amplifier you are combining output of 2 channels to increase the power output. So a left 150 watt channel and a right 150 watt channel bridged will combine power output. The reason to do this is a sub generally will require more power than any other speaker. Also, a sub does not require stereo separation.
Q2: You've got part of what a DSP does. What you are describing is time alignment. Time alignment is a delay of the signal to the speakers. Normally this is measured in milliseconds. The other thing a DSP does is frequency equalization. This allows you to turn down frequency bright spots and add the frequency ranges where your speakers are lacking. This is something that can wait till later if you chose a head unit with a good EQ and time alignment and a set of components with passive crossovers. Those head units tend to be pricy and not offer a lot of other features you may want. Also component speaker can get up there in price.
Q3: I brought Dayton Audio up as an example of inexpensive speakers that sound good. There are plenty of brands out there. Go into some car audio stores and listen around. Post on the other forum I mentioned and get some input from there. You may be able to find some near you willing to let you hear their system and chat with you about car audio. That's where you can learn the most at the quickest pace.
Q4: I prefer to run power cables down the opposite side of the RCA cables and run insulated speaker wire down both sides. The RCA cables are not amplified so interference there will be most noticeable from my experience.
