I'd recommend that you visit
http://www.televue.com/engine/page.asp?cat=2 as part of your reading journey...while I do not always recommend Televue eyepieces, I think that the information here is top notch and worth reading.
Generally speaking, don't forget that in eyepieces like all things "you get what you pay for" and while initially you might not recognize the difference between high quality eyepieces and lessor quality eyepieces if you stay in this hobby a long time you will. I subscribe to the idea that a few highquality eyepieces are better than a case full of low quality one (I usually only use a few (2 or 3) in any one evening anyway.
Visit a viewing night or two with other people and look through as many different types of eyepieces as possible...become an informed consumer.
Lastly, encourage those that want to support your Astro interests at Birthday/Christmas to consider buying a gift card instead of an "unknown" eyepiece.
Having said all of that, use what you have for a while before spending more money...
For example, I would recommend that you get the proper gear and gain the skill of collimation before splashing out on quality eyepieces...a great eyepiece in a poorly collimated scoipe will look horrid!
Good Luck and Clear Skies!
