2.0 or 2.1 can be a serious upgrade if you get a decent pair of speakers. You will loose some surround imaging from a properly set up 5.1 setup, but gain a lot more in stereo imaging, instrument separation, etc.
I have a cmplete 5.2 setup, but have only used 2.0 for the last couple years because it fit the room better.
You have an inexpensive receiver, but Onkyo's entry level stuff is pretty good. Upgrading your main speakers first is a great idea. With your budget you will likely wat to set aside $50 for stands and look at used bookshelf speakers. Start with a 2.0 setup for now. You can try your sub with better speakers, but after upgrading it will probably sound worse than no sub at all so I would consider selling your current speakers to increase your budget.
I havent looked at speakers in a couple years and the the speakers i would normally recommend are not made anymore. I did see that newegg has some martin logan towers on sale this weekend. I havent heard those ones but some of their higher end speakers are good, so they are probably a safe buy. I do recommend auditioning speakers before you buy if possible.
