Sorry to hear you've joined 'the club'. Feel free to post anything on here.
Drugs you might be offered are, Selegiline or Rasagiline, which are both dopamine inhibitors. They help to stop the breakdown of dopamine already in the brain.
Another drug they might suggest is Ropinirole, which is a dopamine agonist. This activates the brain to produce more dopamine and the dose is gradually increased from 2mg. per day to up to 22mg. over a period of time. A word of caution when taking this drug though, as it can have several bad side effects. (Worth reading up on). Some people are fine with it, but others have had to come off it, including me!
One more drug might be Levodopa, but that is usually given later on and to older people.
Your neurologist should let you decide whether or not you want to start taking any medication, depending on how you feel. It's best to start on low doses to see how you get on. Everyone with Parkinson's is different and we don't all react to the meds. in the same way.
People you might want to be referred to are, a physiotherapist (usually 6 sessions), a neuro-psychologist (again 6 sessions), a speech therapist and also the PD nurse, (if your hospital has one). Another very useful person is your local Parkinson's Support Worker who provides practical information and aids, on living with the condition and has a wealth of leaflets to read. Mine came to the house and explained everything to me and my OH, which was very helpful. There is probably a local PD Group that you can join as well, if you feel like socialising with people in a similar position. And of course you can always ring this site's Helpline if anything is bothering you.
The main thing is to try and stay positive and enjoy life as much as possible. Hope some of this helps and hasn't scared you to death!
