Link building/Directory/SEO HELP!

[coykiesaol]

My questions are:

For a Yahoo/BOTW/DMOZ directory submission am I better off waiting until I have more backlinks and a pagerank to submit or should I submit my site now?
Regarding the articles I am posting on the site, should I submit these to other websites, if so which ones?
Are free directories helpful to get, obviously the good ones are but I always see these packages that advertise 2000 free directories, does that help?
Any other helpful advice would be awesome and very much appreciated!
Thanks for reading.

This thing is not disclosed by these directory so I think it won't be better, any new site is also accepted so consider this thing.
