Here's my thinking on this. Upgrading the turntable at this point will tell you nothing about your phono stage. However, upgrading your phono stage will allow you to hear if there are any problems with your turntable/arm combination much better.
Go for the phono stage. Get the best you can afford. The Hana is a really nice cartridge.
Can't help you with what phono stage, as I'm looking at them too, but I have 3 on my short list so far. The PS Audio Stellar Phono on the low end, the Parasound JC 3+ in the middle, and the Herron VTPH-2A on the upper end.
Good luck.
