Submitting to search engines is unnecessary -- they'll find your pages a lot faster through the links pointing to them than they'll ever work through their backlog of submitted pages. Google themselves advise that submission of your pages to them is unnecessary. If you're having trouble
getting Google to index your pages, you'll have better results creating a sitemap and submitting that through
Webmaster Tools than submitting pages directly through some kind of "auto submission" program.
But you'll get the best results by creating "crawlable" site navigation and getting some good links pointing to your pages.
Likewise, auto submitting to directories is probably not a good idea, either. The free directories that are worth submitting to (and there are
very few of them, which makes auto submission a bit of overkill, really) generally frown on automated submissions, because the submissions themselves tend to be of such low quality. If you want to maximize your chances of getting past the editorial review, you probably should take the time to submit by hand, paying attention to the guidelines and standards of each individual directory.
I'm not even sure if you
can auto submit to paid directories, since you have to, well,
pay them in order to be included -- I don't know offhand of any auto submission software that also includes the capability of submitting credit card information to the directory (and if any do, I would be scared to use it for fear of where
else it might be sending my card details when I'm not looking!).
