I'm sure everybody has a noob story from when they started ... first time I built a ROM for my Diamond, my computer overheated and shut down in the middle of flashing to my phone! I thought I was gonna pee my pants! I got on here right away, freaking out, and people responded right away. They told me to stop, take a breath and put it in bootloader. I don't freak out on errors or issues anymore because you can most likely recover from it.
Deimoss and rawdikrik are right, though. Run the kitchen as is once or twice before you start making too many changes.
