Not true. Any Licensed SP can go on as long a solo XC as he or she pleases, without a logbook entry. The only logbook endorsement needed is one from the recommending CFI when you go for your checkride, stating that all PP requirements have been met.
2. you must have a CFI along with you on the night xcountry with 10 full stop landings and get that logbook entry.
Only partly true. Yes, you need night dual. But there is no specific logbook endorsement saying you got night dual - only the checkride authorization cited above.
3. if you did not get an ATC endorsement as an SP, you will need to add that training
True, but as long as you've received the training, there is no requirement that you get the SP airspace endorsement. Besides which, I give airspace training and endorsements all the time to Sport Pilots who are not Student Pilots, or going for any higher ratings. Certificated pilots of all stripes can get additional training and endorsements - this doesn't nexessarily make them student pilots.
4. you must study for and take the PP written, you must get a CFI to sign for that too.
Again, partially true. CFI endorsement for a knowledge test, or
, a certificate of completion from an approved course of study.
5. you must fly two extra hours of under hood with a CFI and get a logbook entry for that
Not exactly. It's three hours total instruction in flight solely by reference to instruments, not two additional hours. And again, the logbook entry does not make you a student pilot. Every pilot gets a logbook endorsement when taking a flight review or instrument proficiency check - but that does not make them student pilots
6. you must take a new checkride and get a CFI to sign off on that too
The Designated Pilot Examiner may or may not be a CFI. Even if he or she happens to be, the DPE is acting as a DPE, not a CFI, while giving a practical test.
Non-CFIs harbor a lot of misconceptions as to what is or isn't required for various ratings. (Sadly, so do many CFIs.)
