My own 102mm f/7 apo is Hoya FCD-1 glass, so a bit below the correction of yours.
Yet, when in focus, there is no visible chromatic aberration, even at 238x.
I, too, am surprised at how good the star images can be. I keep both the focuser and the lens assembly collimated, and, luckily, I did not have
to center any of the 3 objective elements.
As for eyepieces, I can only relate my own considerations:
I needed long eye relief, not because I need it, but because this scope sees a lot of outreach.
I wanted eyepieces completely free from astigmatism.
I wanted eyepieces with good contrast and as close to zero scattered light as I could find.
Due to the short focal length, I could get an acceptably wide field with 1.25" eyepieces. A 24mm Panoptic yields 2.17° which, while nowhere near as wide as
is possible, yields an exit pupil small enough I don't need to wear glasses or use a DioptRx, and is wide enough for nearly any target I would look at in the 4".
So, the 24mm 68° TeleVue Panoptic was my choice for low power. I cannot complain about sharpness or correction or eye relief, though it violates my rule about eye relief.
Typically, I don't go this low (30x) in magnification because of the targets chosen, but it works. A 22mm Nagler would yield a wider field and longer eye relief, and I might go there
As for the rest of the focal lengths, I have a complete set of TeleVue Delites, which I find exemplary for correction, contrast, and spot size.
I chose them because I wanted this scope to be as sharp as possible for its aperture.
I have found their equals in sharpness in some narrower field eyepieces, though not their equals in edge of field correction. And, after years with 100-120° eyepieces,
I find 62° about as narrow as I care to go. It still seems narrow, but the fields are wide enough with the short focal length scope. If the focal length of the scope were longer,
I might have opted for 70° or more.
Having the complete set, I would argue that one does not need the full set of Delites to provide adequate magnification choices.
I will probably pare my set down to:
24mm, 15mm, 9 or 11mm, 7mm, 5mm, 4mm, 3mm.
The 18.2mm Delite is used a lot, though, so it seems difficult to part with that one. And the 13mm seems to spend a lot of time in the focuser as well, so another one to keep?
Aw, I just have to face it--I like having the whole set, because each plays a rôle in the framing of particular targets.
Now, if keeping it economy, there are some very nice inexpensive long eye relief eyepieces out there (22mm Olivon 70 comes to mind--it works really well in the apo), and if you don't mind the price of the Delites but want wider fields, the Baader Morpheus comes to mind, or the APM UltraFlatField. I recommend an eyepiece to yield ~50x and another to yield ~100x. Other than that, your choice.
I suggest downloading the Eyepieces Buyers Guide at the top of the eyepieces forum and then whittling it down to your possibles and then getting feedback on these forums.
