@Blaw-
Tested the NEW "patchPSGEN2.py" from 19:00 to 21:00 creating a NEW ISO. Here the Results:

SO WE SHOULD SAY THAT (at least for emulator BUG is resolved).
Now let's answer your question:
1) Yeah English have icon BUT i rebuild mine from FRENCH VERSION. As said in OP, I managed to extract all ENGLISH files with CUE's Tool NOT Algoring which failed with strange BUG, so i take the extracted/dumped items/script and rearranged into
"FRENCH"ALGORING to "RE-CREATE" English version.
I've uploaded for you my FONT directory + "bf-encoding.txt" + "bf-width.txt" so you should only replace in yours, it was edited like explained to SandyLandale in previous post.
2) Sorry but i can't find LEVEL35 TECH for KEINZ...also the name isn't present in the game....perhaps you mean Forsa but it's a LV2 TECH..please explain better..now that I have the opportunity i would like to test it...
3) Problem is for KEINZ TECH & ZAN TECH (wind) if you watch carefully in original "011.txt" you'll note that some GADGE technique description have multiple pointer for the same description, this means that different technique has the same description (the error comes from this). I have inserted my 011.txt into the RAR so you can easily understand what i mean comparing yours with mine ...I simply splitted the pointer and give them a new description...fitting what they do ingame
4) For Rudger name i can't share my file simply because english and french are completely different and you can't utilize it. For resizing RUDGER you have to open 005.png of directory MAPDATA.DAT into phostoshop and slightly transform it. After you have modified PNG delete the corresponding 005.bitmap that's because if algoring finds it in the compilation it will use the OLD and NOT RE-CREATE the new. It works like this: If algoring finds the PNG and not BITMAP it recreates the BITMAP based on PNG and VICEVERSA. I suggest to work on PNG because BITMAP is much more difficult. ALSO PAY ATTENTION to FINAL FORM of PNG..IT MUST BE 24bit!!! and not 32!!
5)Nothing here for you..the original english version had weapon and element inverted
6)Yeah, and its the EXACT CONTRARY...MY TABLE IS TOO SMALL!!! I had to add all items and equipment..
Here is the RAR:
