Keyword Suggestions
 

How to suggest keywords whether to choose high searches and low competition or low searches and high competition or both searches and competition should be equal?

Your keyword strategy should depend upon what you are planning to promote and how. Using the Keyword Planner you can get a list of keywords to choose from. There are various other methods to pick the right set of keywords for your page. Getting expert help should not be a big problem. Ideally, do it yourself and learn from your mistakes. :)

Follow high searches and low competition trend from Google AdWords and trends tools.

Market Samurai is good, i wouldnt buy it (expensive) but if you download the trial (40 days) then you can use it for initial research.

Use Google webmaster tool to search best keywords. Its perfection and features really impress you.

I completely agree with you, along with the Google keyword planner Google Analytic and Webmaster tool can help you to select the right keyword for your website.
