Hi Gary &

Now that's what I like to hear- someone who's done their research and read thru the forums- good on you!
I don't think anyone ever forgets their first Saturn experience. It's very much like the "first time" of ..... ahemm you know what I mean- only better.

No one's yet been able to make my heart palpitate like Saturn did.

You may be interested in an article which I did, listing easy to find, bright targets for beginners for what's in our sky at the moment. The LMC- if you're up for a very late night or early wake up call, should be high enough around 4am (check Stellarium). It's not on the list but will be in my forthcoming Summer list when it rises earlier. So much to explore there- it's crazy seeing star clusters and nebula in another galaxy!
The Virgo galaxy group isn't on my list as they're faint and may require a bit of experience to star hop and find- but have a go- it's in our sky at the moment. There are something like a thousand galaxies in Virgo! Just in one degree of sky alone, you can find 10 galaxies as in
Markarian's Chain (which includes Virgo A- a giant elliptical galaxy & radio source). If you get a chance- & if you're up for a challenge- and you're 10" will be very capable of performing this task- have a go! Start with your 25mm to find it, then swap to the 10mm to observe. When I tried the 15mm on my 10" dob each time I've looked at them they were very tiny, the 10mm brought them up bigger & better to observe them.
Highlights of the Winter Sky
Regarding the focal lengths of your eyepieces, as a guide:
The 9mm & 6mm will be good for planets (going to 6mm depends on sky)
The 15mm & 10mm will be good for galaxies (sometimes the 6mm if the galaxy is bright enough and conditions are good)
The 15mm will be good for globular clusters
The 25mm will be good for open clusters and finding things in general.
