salam alaikum dear brother and welcome to islam.

Subhana'Allah I pray that Insha'Allah Allah swt makes the staight path easy for you and makes you a firm believer in your heart and gives you true guidance.

the actual way to greet a fellow muslim brother or sister is:
Asalam alaikum wa rahtmatullahi wa barakatuh.
but that is rarely used,
some say:asalam alaikum
some say: salam alaikum
others even say: salam

in most cases the reply to that greeting usually is:
walikum asalam

regards the dos and donts of islam, brother i suggest you get the Qur'an and read it thats where you will find all the answers to that.

when you want to meet a muslim woman? as in get in a relationship with her? or marry her?
well for starters pre marital relatsionships in islam are forbidden so im sorry but you cannot walk to a muslim sister and say "asalam alaikum wa rahmatullahi wa baraktuh, so what you saying you wanna be my girlfriend or what?"

as regards marriage brother you just embraced islam i suggest you learn about your new religion 1st then go on the quest for hunting for a wife.
but remember one thing brother when it is written for you only then by Allah swt's will, will it happen. no matter if your desperate to get married or dont want to get married at all. it is all Allah swt's decree.

so rest assured in that aspect insha'Allah when its meant to be it will be.

i suggest that you start off with google, do searches on way to perform salah and start with your salah 1st cos that is one thing that will strengthen your eeman (faith) and in just by doing so as in performing your salah and being steadfast in it you naturally and autmatically abstain from doing wrong.
then make the Qur'an your best friend, read it and try to implement it in your life.

then once you have grasped the above start getting more into it, but i think the above is a good starter and i pray that Insha'Allah Allah swt bestows His mercy and guidance upon you.

Ma salama. (peace)
