Basically I want to learn how to use the kerning, spacing, ligatures to make it more legible. If any one knows any tutorials or guide available online please let me know.
And to get help creating a really good font I'd suggest joining a great forum like Typophile. There are many experts and world renown typographers there that give practical advice and help to others. They'll give you constructive critique of your work and help you get the most out of it.
