How to begin with the meeting with my former teacher without contact for 3 years

I am going to meet my former teacher in my former school. We have some interests and hobbies in common, but we had not been in contact for several years,

I should be more careful of the etiquette and manner.

I don't want make she think me impolite by beginning with the conversation with sentences like "Hello Prof. ABC. How was your recent journey in Japan? Had you

brought me a souvenir of Tokyo?"

She has agreed to write a few recommendation letters for me to apply for multiple programs at several universities.

Should I say "Can we talk about my recommendation letters first because you have argreed to help me..."

I am a bit nervous for the meething with her this Friday.
