1458 Directory Submissions in 2 weeks?

Well let me try to answer your questions:

1. Directory links may not be very beneficial for good rankings but still this is used by most of the SEO's because every link to your site gets counted. There are some good directories like DMoz, Yahoo Directory, BOTW etc. that are really good.

2. I don't think it may trigger any such spam filter in Google because first of all if you submit to that much of directories, you don't get accepted in all of them at once. Some may approve your link in 10 days, some may take 3 months and some 6 months. After that it is not necessary that all links will be cached at the same time by Google. So there is no such issue like excessive backlink building in this approach.

3. I always submit some articles in good article sites like Ezine articles, Buzzel etc for a new website. These articles get cached quickly and so as your website. I also use directory submission for my new website.

Thanks Neno for your detailed response. I will def take up article marketing and rump up what am doing at the moment.

I am completely agree with neno. Link is a link and directory submissions link is also counted and they are not considered as spam. But the main thing is that the "QUALITY". Directory links are not of that much quality.

As long as their not spammy sources you should be ok. Might want to take it down a gear to not tip off the big G though.
