1. Instead of marking those which are safe to remove, I would mark the apk's which are needed for the phones's essential functions and which should not be removed. The rest may be some eye candy (i.e. wallpapers), or some features not everyone uses (examples: Teethering, TV launcher), or apps that may be redundant to some (example: Gmail, Email does the same). Their removal is subjective to each individual.
2. My comments after ->
ArtFilterCamera.apk ==== Useful for the camera -> these are mostly cheesy filter effects, IMO
BlackThemeBlueAccent.apk ==== Black Blue Accent Theme=== Safe to remove -> Themes come with build in accents but if you don't choose a theme that has accents, then you will have none. And also no check marks on check boxes, colours on toggles, etc.. My take: Don't remove.
BlueTheme.apk ==== Blue Theme=== Safe to remove -> it is the theme Air
HTMLViewer.apk ==== HTML viewer -> to my opinion safe to remove, haven't found any need to see html files outside the brower
NoiseField.apk ==== ? -> noise surpression for the mic
OnOffTools.apk ==== Related to the launcher probably -> threse are the Sony on/off toggle widgets
PartnerBookmarksProvider.apk ==== Bookmarks Related -> safe to remove
PicoTts.apk ==== Text To Speech Service -> safe to remove, keep the Google TTS, IMO
RemoteControlService.apk ==== ? -> That's the "find my phone and erase everything on it" feature, in case it's lost. If checked in settings, it also enables continuous phone location tracking and detail location storage on Google servers.
SemcAlbum.apk ==== Sony's Album=== Safe to remove -> I'd not remove that without having another one.
SemcEmail.apk ==== Sony's email app=== Safe to remove -> not present on my V
SEMCSetupWizard.apk ==== Setup Wizard -> safe to remove only needed for noobs, all setings can be done manually
SemcWarrantyTime.apk ==== ? -> exactly what is says, warranty timer
ShareApplication.apk ==== Share Application -> part of the social engine = safe removal
SomcXperiaLink.apk ==== Xperia Link -> easy connection to other Sony Link enabled devices
UpdateCenter.apk ==== Update Center -> not needed on non-stock roms
VpnDialogs.apk ==== VPN Dialogues -> safe to rfemove if you don't use VPN
3. Does anybody have a BlackThemeBlueAccent.apk for me?
Thanks once again for the gargantuan task you undertook!
