Forget about submitting to search engines - it's a waste of time.

Just get links to your website from established and frequently crawled websites like lowyat.net, e.g. add the link in your signature. You can also add your site in Google's Webmaster Tools.

Websites are indexed in batches so there maybe a lag. Google also use different servers for the search results so you have to wait slightly longer for it to be reflected on all their servers.

To check which pages are indexed, just go to Google and enter into the searchbox "site:yourdomain.com" (without the quotes).

The search engines are smart enough these days, so it doesn't matter. However, you should use "-" just to be extra safe, e.g. frasers-hill.jpg
