The only advice I can really give is to have fun. Don't think too much about it, just take pictures of anything and everything you want.
Try things out, experiments here and there, take it easy, it's a hobby, quite a fun one even.
If you have friends/colleagues/... with photography experience you can ask them to judge your pictures, take what they say with a grain of salt as if they are experienced, their ways of shooting might not be yours.
By taking more and more pictures, you will naturally find things that you like to do and others that you won't like and slowly your own style will show up in your pictures.
Photography is a very personal thing, it has to please you first. If that shot also happens to appeal to others, that's even better.
As for the technique, just stick to auto at first and slowly learn up things like the Aperture, ISO, speed, composition,...
Gear wise, you are pretty much set for most things, there will be very little need for more except when you will start getting picky about your pictures, even so you can still make do with what you currently have.
