Long tail and brand related keywords are typically worth more than shorter and vague keywords because they typically occur later in the buying cycle and are associated with a greater level of implied intent.

When people use keyword stuffed copy it tends to read mechanically (and thus does not convert well and is not link worthy), plus some pages that are crafted with just the core keyword in mind often lack semantically related words and modifiers from the related vocabulary (and that causes the pages to rank poorly as well).

Example keyword discovery methods:

• using keyword research tools
• looking at analytics data or your server logs
• looking at page copy on competing sites
• reading customer feedback
• placing a search box on your site and seeing what people are looking for
• talking to customers to ask how and why they found and chose your business

Short list of the most popular keyword research tools:

• SEO Book Keyword Research Tool - free, driven by Overture, this tool cross references all of my favorite keyword research tools. In addition to linking to traditional keyword research tools, it also links to tools such as Google Suggest, Buzz related tools, vertical databases, social bookmarking and tagging sites, and latent semantic indexing related tools.
• Overture - free, powered from Yahoo! search data. Heavily biased toward over representing commercial queries, combines singular and plural versions of a keyword into a single data point.
• Google - free, powered from Google search data.
• Wordtracker - paid, powered from Dogpile and MetaCrawler. Due to small sample size their keyword database may be easy to spam.

Please note that most keyword research tools used alone are going to be highly inaccurate at giving exact quantitative search volumes. The tools are better for qualitative measurements. To test the exact volume for a keyword it may make sense to set up a test Google AdWords campaign.
