I'll field a few...

1: The init processes is the mother of all processes. It usually (unless you have some sort of odd kernel setup) has a PID of 1. It is the first process run in user space and is in charge of launching other processes, which in turn launch other processes, and so on.

2 & 3: Here is a nice list of the normal Linux run levels.
1 - Single User Mode
2 - Single User Mode with Networking
3 - Multi-User Mode - boot up in text mode
4 - Not yet Defined
5 - Multi-User Mode - boot up in X Windows
6 - Shutdown
You can change runlevels on boot by passing in the number (or the word single for single user mode) as a command line parameter. Once the system is booting typing init <runlevel number> on a command line (as root) will change your current runlevel.


5: The bootloader is the program installed into either the MBR (master boot record) or the first block or so of a particular partition which the bios executes after doing all its startup diagnostics. There are several differences between LILO and GRUB, but I think of GRUB has a more modern, more flexible bootloader.

6: Exact procedure depends on the boot loader your using. If your using grub then edit your /boot/grub/menu.lst (might also be called grub.conf) file. Set the default parameter to whatever choice you want the default to be (numbering starts at 0). Set the timeout to 0. I actually recommend having it wait 2 seconds so it isn't such a pain if you have trouble getting Fedora to boot.

7: NTFS isn't supported well under Linux as it is a propriety fs with no specs. The LInux kernel can give you read-only support for NTFS. Captive can give you read/write support. I've never used Captive.. so I can't make any claims to how well it works.
