Awesome scope, great choice
Maybe you can beef up the quality of your ~10mm. 125x and upto 150x magnification is really useful for all round viewing and a nice wide angle eyepiece will be fabulous. Older 9mm Naglers come and go for 300-350 bucks in the classifieds and they are (ironically) keepers. You need some more power for the planets, but that's where logic gets turned upside down a bit. Simple and relatively cheap eyepieces can do extremely well on planets because you are looking on-axis and don't need a wide field of view. A 4mm or 5mm would probably be enough.
If you can, hook up with a club and try before you buy, you will get priceless advice from the regulars!
