Hello and welcome to the forums where I hope you will find emotional support and from many experienced people who have MS or those who are in limbo waiting for a diagnosis.
I would like to state first that as much as we are all interested in what you have to say, and we are, is when you type out your question, that you break it up for those who have trouble reading.
As for your Neurologist visit, good for you. You need to go.
So far you have listed:
Fatigue (severe)
Paresthesias (numbness/tingling/cold sensation)
Cognitive dysfunction (memory & foggy)
Dizziness
Pain
Headaches (lots of people have headaches without MS and most MSers have headaches, sort of hard to tell if MS actually causes the headaches).
However, the symptoms you've listed and the very fact that you are no longer working due to your extreme fatigue and most likely poor performance due to pain and other issues, is a reason to seek a Neurological consult.
Can it be MS? Maybe. Are there other things that cause these symptoms? Yes. Such as: Vitamin B12 deficiency (something as simple as that), Hypothryoidism (which I'm sure you were tested for that), Lyme disease (which I'm sure you were tested for that), Lupus, the list goes on and on and there are many conditions that can cause those very symptoms. MS has a lot of mimics.
So, what to expect when you go see your Neurologist? Hopefully his assessment will take a long time. Properly done, your visit is approximately about 2 hours. He will take a history (surgical and medical), ask about your symptoms or what brought you there, do a neurological assessment on you (testing reflexes, etc.) and sit down and discuss the plan of care for you.
He will most likely order a MRI of the head, cervical spine and thoracic spine, with and without contrast. Probably order some blood work your primary had not done. (Good idea to get your laboratory results from your doctors office, ER visits (can go to medical records, sign a form and obtain your blood work or any other diagnostic test BEFORE your appointment.)
Again, welcome to the community and I hope we can be of some support to you.

PS - We have health care pages you can take the time to read here:
http://www.medhelp.org/health_pages/list?cid=36
There is a plethora of great reading in there.
I find it important for people to educate themselves as they journey their way into finding out what is going on with their bodies, particularly if you suspect MS (or if your doctors do to).
Only thing I suggest is when you go to the Neurologist not to mention what you or your friends "THINK" it is, let him be the doctor and see what he comes up with. If he sounds like any of the wanks in the hospital, then we'll come up with another plan for you. :)
Hope I was helpful
