Welcome aboard!
I'll answer your question "basically" and then leave specific recommendations to others...
I'll also recommend some reading on the Televue website...
http://www.televue.com
Yes, I know most their gear will fall outside of your specified price range but the advice is still solid (I think)...The article about "Choosing an eyepeice" and the other article about "Eyepeice choices for a small dobsonian" I think are worth reading...while 10 inch is not necessarily "small" I still think the article makes some sense.
Here is my two cents...I'd recommend getting a few better quality eyepieces instead of a whole bunch of less expensive ones. Quality holds it's value if/when you decide to exit the hobby or trade gear...also if you enjoy it for a lifetime it is still money well spent and you get a lifetime of enjoyment out of some quality stuff...I tend to save and get one "high quality" eyepiece at a time...but that just is me.
Numero uno recommendation is to encourage you to get a good chesire collimation eyepiece...don't mess with lasers for a while...a good chesire will last forever and you will use it everytime you set your scope up...
In general, I'd recommend getting 3 eyepeices...a low power (50x magnification), a medium power (around 100x) and a high power (175x eyepiece)...
However, first up I'd encourage you to get your scope out with whatever eyepeice(s) come with it and use it for a while before spending any money on any additional eyepeices...
I'd strongly encourage you to meet up with others in an Astro Society (join one if you are not a member) or hook up with some other IIS folks and look through their eyepeices and try them in your scope...most people are happy to share...once you know what you like then shop away...but remember, you can not beat trying it before you buy it.
Best of Luck and Clear Skies!
