My question involves criminal law for the state of: Virginia

I have recently been charged with possession of marijuana(less than 14 grams). I have a summons from the police. The story is I was at a party, cops came in because of the smell of marijuana. I hid my stash, but when the cops ask for if anyone has any I told them and gave them what was mine(better than blaming others).

My questions are:

Do they mail anything to your house about the charge that I will need to know?

What will happen when I go to my 1st court date schedule?

I know it is not beatable, but what can I do to lower the offense or even get dismissed?

Can I make it easy by myself, I do not have money to pay for a lawyer can I get through with just myself?
