I myself use a 24AH SLA for my LX90 but, only because I already had one lying around & also because I use it for my EQ mount & AP setup.
I generally find the LX90 Az/Alt not very power hungry vice the EQ / AP rig which sucks power like it's going out of fashion.
Regarding AP, I highly recommend a bhatinov mask to ensure that you have really sharp focus; these can be found on e-bay for as little as $16. Have a look for the e-bay handle 'I_like_vegemite', that is who I purchased mine from & he will design one for you if he doesn't have an exact match.. I have no idea who he is but, he is in Melb & his products are really good.
For planetary work, use video.. this allows you to capture thousands of frames over a short period of time; stack the video in Autostakkert, sharpen in Registax & final tweak in digital photo processing software of your choice...
I considered a wedge for my LX90 (both commercial & home made), in the end I bought an EQ mount & separate scope & do my deep sky that way instead. I understand though that there are plenty of people out there getting great results of a wedge....
Eyepieces, depends on what you want to do.. I have no experience with the Saxon range you mention but, I have Meade UWA's for widefield (a whole 1.3 degree FOV max in the LX90) & KK Fujiyama Orthos for planetary. I also have a full set of Meade plossls that came with the scope when I purchased it second hand; the plossls are fine, the others are better but, the plossls are fine...
Can't speak for your red dot finder but, I use a Bintel one which is quite robust however, that said, if the one you have is working fine I wouldn't bother changing it until it breaks.... It only has one job really, helping you get that fat 8" tube onto alignment stars... after that, if you have been exact in your alignment stars the goto should handle the rest...
I'm sure others will chime in with ideas for you as well but, hopefully, this helps...
Cheers

Pretty much sums it up.
Nothing much wrong with the Red Dot Finder that comes with the SE8.
Was also considering a wedge for my SE8 but have decided to go with an EQ mount when I can afford it. At 800 bucks i'm thinking money would be better spent on the EQ rather than a Wedge.
I would also recommend the Baader Hyperion Zoom Eyepiece 8-24mm. I hardly use any other eyepieces these days. the 31mm or the 36mm Baader Hyperion eyepieces are good for doing the your alignment.
A Focal Reducer/Corrector is a must. Celestron's 6.3 is excellent...
