Should I do Minecraft videos?

Ok so I really like playing Minecraft and I want to do more than just the regular stuff so I have been thinking about making Minecraft videos and putting them on youtube. I'm 13 and homeschooled so I have enough time. My friends and family all love watching me play it but I don't know if anyone else would. If I do decide to do it, I don't know anything about recording the videos so I would need to know these these things.
1. Do I need a microphone or anything to talk into?
2. How do I start the actual recording?
3. After I record the video, how do I edit it?
4. Is everything that it takes to make a Minecraft video free?
5. How much of my time would it take if I put 1 video on youtube every week?
6. I don't want to do this for money or anything, just so I can entertain people. So will I get money for doing this?

Added (1). Oh and I have the PC version

Mojang has never sent response in support center for minecraft?

For months, I haven't been able to log into minecraft.

PC good enough to run DayZ?

For the past month I've been trying to decide wether I want to buy or build a PC. I want a good enough PC to run DayZ, Minecraft, and all that good stuff. If someone could maybe suggest a good PC that I could buy from Best Buy or something (sorry if you're face palming idek) because I have not the slightest clue on how to build a gaming PC. If you could put links to websites or whatever I'd really appreciate it!

I'm trying to sign my little sister up for Minecraft and no matter what I type in for a username, it's taken.

How to make chunks load faster in minecraft?

So my computer will run minecraft at 80 FPS at the highest possible settings, but when chunks start to load it drops to around 40FPS and sometimes much less. Is there any possible ways to make chunks load faster? Could I put Minecraft on a Ramdisk? Should I upgrade to a SSD? Should I increase my RAM from 6 to 8GB? Anything? (i don't know if any of those will do anything, i'm just spitting out random things).

I have 64-bit windows 8 with 64-bit java. (i don't know if thats relevant)
