Quality Backlinks?

I'm new posting here, but i have read the forums over and over. Anyway I'm having problems getting my backlinks built up. Although i know the methods that are most commonly mentioned, commenting on do-follow blogs, forums and so on i still seem to have problems finding the place to leave the link.

I don't really know how to go about finding blogs in my same niche or forums even, which is where i'm running into a problem. The other thing is since i'm new to all this, after i post a link on a do-follow or get posted on an online database how long does it usually take for a search engine to see that link and give it weight?

Don't want to sound like an a$s, but the search function is < and ^

There's a ton of resources on this forum, so chances are you haven't read the forum over and over.

I use tools like Scrapebox to greatly reduce my research time for finding domains/pages/blogs/etc, anything I need for SEO as it can do huge PR checks, alexa ranking, and just about a million other checks you'll need throughout the process.
