If you have a factory deck, just use the power from that to power the door speakers. If you have an aftermarket deck, you could do the same because it is the cheapest route.

You could run two amps. If you run 2 amps, I would suggest 4ga from the battery to a capacitor. Then 4ga to the distribution block. Then from the distribution block I would run 8ga to the amps.

You can't really have someone choose door speakers for you because it is all about personal preference. People can suggest stuff for you to look at, but they all have different qualities. Companies like MB Quart have a habit of being "tinny" on the highs. Look through JBL's selection of full range speakers and see if anything interests you.

You could go with a component set up front, but they tend to cost more then standard coaxials. But they offer better sound quality and sound direction then standard coaxials.

I'm a big fan matching speakers, and matching electronics. Mainly because the same manufacturer will have the same tonal qualities throughout the audio spectrum. With electronics (amps, signal processors, etc), I like them to match just because they seem to work together better.

So the end choice is really up to you. First thing you ALWAYS do when thinking about car audio, is to figure your budget. That is the VERY first thing anyone should do when thinking about car audio.
