I agree, you could also go with the smaller bookshelf speakers like the A3's if you wanted to mount them on the wall.
Either way if your looking to save cash, check this site often:
http://stores.ebay.com/Polk-Audio-Direct
Its Polks official refurb store. You not only get a factory refurb product which ALWAYS looks just like new (ask all the happy folks on this forum who bought from that site), but it comes with a
warranty as well.
Here is a setup from that site I would go with:
Cherry RTi 8's (equivalent of the A5's I believe): 400
Cherry CSi5 (equivalent of the A6 center now): 225
That site also has the RTi 8's in black as well as a Black RTi A4 center that would save you about 75 bucks, but I would go with the first system since its 100% timbre matched and the finishes will be the same.
The RTi line is a VERY nice step up from the Monitors. Also the RT in RTi stands for Reference Theater..... so they are created with the intented use for HT which is what you want. They also do music much better than the Monitors, but not as good as the LSi's or LSiM's obviously

Then once you have more cash I would upgrade your Onkyo before your surrounds. The Onkyo has enough power to drive those speakers, but you will be shocked how nice they sound hooked to either a Onkyo with more power, or to a dedicated amp. It will make those speakers thump and sound much better.
That said you dont
have to upgrade your Onkyo right away as you will still be able to enjoy the better sound they have with your current one. I would simply plan on eventually upgrading your Onkyo to either one with more power or the prefered method of a Onkyo with pre-outs and a dedicated amp if you can.
