changing "o" to "u"
Do you only change "o" to "u" when it precedes a word that begins with "o"? What about AFTER a word that ENDS in "o"?

It only changes when the next word begins with "u". After a word ending with "o" you use the "o" (unless the next begins with "o", of course).
Also used between pairs of digits "4 u 5". This presumably has nothing to do with sound but with avoiding confusion btweeen the letter "o" and the digit "0".
Uno u otro.... yes
