It's going to be worth trying out some different string types as you get round to changing strings. I'd certainly go a bit heavier than your .009"s and at least try .010"s. Also try fitting acoustic strings. There's a reason they don't fit electric guitar strings to acoustics; they just sound so much thinner.

I suggest that you try out different string types and thicknesses, as it's all about matching the string characteristics to your guitar characteristics for the best sounding results. You may find that light electric strings sound best on it, or it may sound better with slightly heavier phosphor bronze strings. You may even find that the intonation improves by changing string type or thickness (though it could also be made worse). It's going to cost a few dollars to experiment, but I think it would be worthwhile to do. It is a very nice looking guitar indeed and deserves every chance to sound its best.
