109F Ace Maker is nothing but a reprint of the two Kagero Bf 109F monographs with a few new (smaller) profiles. Recommended only if you don't have the previous volumes. Covers development, unit history, 1/48 and 1/32 scale plans, aircraft manual pictures and plenty of photos.
109 Recognition Manual...100% technical stuff and photos. Lists production versions, rüstsätze/umbau variants, weapons and equipment.
Ju 88 part one. I quote the cover "Development - Production - Technical History." Also covers Ju 188, 288 and 388.
No idea if the 109 Recognition Manual is available, but the other two are.
Can't help with the Spitfire book.
