First time offender....what is going to happen??

Ok...so this is my first offense ever, so I am completely unknowledgeable as to what is going to happen or how to handle this.

I live in California. I have a notice to appear in court.

"This is to advise you that a misdemeanor complaint has been filed against you for the violation of:

PC 503 Embezzlement
PC 459/460(b) Second Degree Commercial Burglary
PC 487(a) Grand Theft of Personal Property"

So basically, I have a few questions that I would extremely appreciate any help with...

1) What is a range of what could happen to me and the probability of going to jail. I believe the amount in question comes to about $7,000 in merchandise.

2) When I go in to the court, will I be asked for a plea....and if I want a public defender, what should my plea be?

3) Will the Grand Theft charge, or any of them, be filed as a felony even though the notice says "a misdemeanor complaint"?

So basically....I have a million things I could ask...so any help or insight will be greatly appreciated. Thank you

You need to hire a lawyer frankly if you can. The public defender should be your last resort. With 7000 dollars missing jail is possible.

Don't mess around guessing the system. Whatever you have to do, hire a senior criminal law lawyer.
