That TT thread is great, certainly go read it. With your focus on just this 10k TT, and with you being new to this, I'd recommend you focus on a couple high intensity intervals close to your expected 10k time. I generally cover the distance on the 13-14 minute range depending on the course. Start out at 70% effort for the first half, gradually increase that during the second half. Remember your body position, stay low. Try to finish with nothing in the tank and your HR spiked.
Good luck!
