Hi Hope,
I wish you luck and trust you'll keep going longer than I managed last year (just 17 weeks, even though I had photos taken as far as week 23).
You have received a lot of good advice above and I cannot really improve upon it.
Here is the index post to everyone's P52 threads from 2012.
Project 52: Index and FAQ
My 'angle' was to try to provide something "instructional" for members, but I found this just took too much time to prepare and I am ashamed to say I lost interest - however, you may find them helpful.

I would recommend separate threads, perhaps with a link back to an Index post, (like I did for Week 17)
Good luck,
