If you want to get to grips with hieroglyphs quickly, then you ought to start with Bill Manley's "Egyptian hieroglyphs for complete beginners."
It's less than $20 and worth every cent. Manley uses real inscriptions as the basis for your learning and, unlike many books which start with grammar, Manley's book enables you to get to grips with words, phrases and common formulae so you'll develop competence and confidence quickly.
Within a couple of weeks you should be able to read quite a lot of information on Middle Egyptian stelae, sarcophagi and coffins.
Then, I'd move onto his "How to Read Egyptian Hieroglyphs" but make sure you get the revised edition. By this point, you'll be ready to start tackling the grammar and will be surprised at how much you have picked up!
However, I am sure that the hieroglyphs at the Hathor temple are written in "Late Egyptian" which I am unable to read as this does not derive from Middle Egyptian, which is based on a different dialect. The difference between Middle and Late Egyptian is greater than the one between Middle and Old Egyptian.
My point is that most books will teach you how to read Middle Egyptian, as Manley's books do. Study of Middle Egyptian won't enable you to read the inscriptions around what you believe to be a depiction of some kind of 'plasma tube' unfortunately.
Frank Doernenburg may be better able to help you in this respect.
The first image in your post is another offering scene; there is an offering written vertically behind the woman who stands in a pose of veneration to the deity Horus, as Re-Horakhty. A thousand loaves, beer, oxen and fowl are offered and he, in turn, showers her with blessings, expressed visually as what I assume are flowers.
The other image I know nothing of; it looks scientific and I profess to know nothing of science.
