How can submit my site to Google and Alexa
I don't know about Alexa, but don't count on Google finding you unless
your site is linked to from other places. One good place to link to your site is your signature here (see my signature?). GoogleBot crawls phpBB.com frequently.

I don't know what you mean. Once Google finds your site, it
will index your pages. You could also use a site map, but that's only necessary if Google can't crawl your site -- and Google can very easily crawl phpBB.
You don't need much SEO at all. My dog sitting site is #2 in Google on various searches (like Hollister dog sitting
) and I never submitted it to Google and the only "SEO" that I did was submit my site to a couple of pet sitting registries and ensure that the area that we served was mentioned on the home page.
