Great, simple system -- sensible, balanced, perfect for the room it's in.
My only suggestion would be to investigate a different phono stage if you happen to be looking for a little more life, air and wider, deeper soundstaging. I own a Technics 1200, reviewed the Pro S30 and owned a Grado preamp at one time but I keep coming back to two phono stages for use with the Technics: Todd The Vinyl Junkie's Millett Hybrid for $850, and Pro-Ject's Tube Box II SE for $700. They'll also give you more flexibility in terms of loading so you'll have more options in case you ever decide to try a different cartridge.
Oh, and check out the Herbie's Way mat for the Technics. That's a cheap upgrade that provides a very noticeable improvement. The KAB Fluid Damper and Sumiko HS-12 headshell (should you ever change to a standard-mount cartridge) are nice, affordable upgrades, too.
Aside from some fun, beer-budget tweaking, I say you've got a system that you can own and enjoy for years and years to come. Congrats!
