[SIZE=+1]Q2: What does S-OFF/S-ON mean....?[/SIZE]

On HTC devices, the manufacturers enables a security flag on the Nand memory. When you root your phone, you are only given access over the system, meaning that you can flash custom firmware. However, this NAND-lock prevents you from flashing unsigned images to restricted partitions including, but varying by HTC device, the boot partition (where the kernel and other information is stored), the recovery partition, the radio partition, and sometimes others. So due to this NAND-lock, fully rooting an HTC device typically includes gaining S-OFF on said device in order to have full control over the device, be able to update radios/modems as they come out, and other [usually] essentials.​

[SIZE=+1]Q4: What is fastboot/bootloader mode....?[/SIZE]

On some Android devices there is a "fastboot" mode by which custom firmware can be flashed after unlocking the device (root). The bootloader is a part of the boot sequence that provides access to fastboot and recovery mode, as well as the normal system. Note that using most fastboot commands requires a rooted/unlocked device.​

[SIZE=+1]Q5: What is a recovery....?[/SIZE]

A recovery is an OS-like portion of the device that lives on its own partition. This specific design is a product of Android itself that allows updating of the device. When a custom recovery is installed, custom firmware packages (not released by the carrier/manufacturer) can be flashed to the device, as well as other packages.​

[SIZE=+1]Q6: Where can I learn to dev....?[/SIZE]

There are MANY good places to get started. In my personal opinion, you should read through the entire xda-university site, as well as searching around on XDA and reading whatever catches your eye. I cannot stress enough how important reading and understanding is. Some other good places to look include the following, in no particular order:
