I'd buy just the SSD, put it in your 2010 Mini and see how it is. It makes a world of difference.
If you still find it lacking, you can at least take the drive to the new Mini. It'd still work out cheaper than what Apple charges for it, so you don't really have anything to lose.
I'm not sure I'd bother buying what I assume is DDR2 RAM at this point. It isn't that cheap and won't transfer. 4GB isn't too bad for 2010, anyways.
I suspect that you'd be happy with the SSD in the 2010, ultimately. I've even put one in a 2008 Core 2 Duo PC laptop and it isn't half bad at standard stuff.
