I thought I had a scratch on my new primary mirror, It diddn't matter which way I looked at it, I would have put my money on it being a scratch. It turned out to be a hair. I'm hoping for you, hope it turns out the same!
Regarding collimation
www.andysshotglass.com is brilliant!
All the best and I hope the frustration subsides soon so you can start enjoying the Heavens like you've set out to do!
Cheers Brad
