Just my opinion - I would try a SCART lead in a few flat scrrenTVs first. Lot of research done here, they work pretty good if they are built right;-

https://ilesj.wordpress.com/2012/01/25/brilliant-picture-from-amiga-with-rgb-scart/I'm going to have to do this at some stage for my equipment, so I might go 23-15 VGA first, then see if I can build a combined unit that does VGA or SCART at the flick of a switch.
That way I get lowres and flicker free Productivity on the same screen without too much fooling around. I don't game much if at all, so this approach makes sense for me. Most people would do it the other way around.
Accelerators on 3.9? Accelerators any Amiga, you see some difference. Depends what software you are running. Things like MUI apps tend to lag without, in my experience anyway.
Listen to Mike on upgrades, he's been there, I haven't.
+1 I would pickup a Indivision AGA unit. It makes a big difference on modern LCD monitors even widescreen ones. CRT would be good for retro scanlines but definitely LCD would look better..
Flickerfixers have been, are, and will be awesome on Amiga.
