Mandie this is wonderful news! Of course you have to keep a watch on this movement. What they are looking for is hand to mouth movement without the assistance of gravity at about 4 months. But it sounds like your sweetypie is getting there!!
A neurologist appointment is usually pretty benign. They look and ask you questions - check ranges - do some neurological tests with some toys. They may take a sharp point and see if she has feeling in her arm. They'll try to make her look right and left and up and down. They will check for reflexes in her arm. It shouldn't be upsetting at all to the baby (if he/she has good bedside manner of course).
Here's a page that will give you a lot of information:
it's on the home page of this site - click on the button that says info for new parents (middle right side).
Also - here's a place that is chock full of information:

Also - the best advice I can give you is to get your little one to a bpi specialist just to have a look-see. There is a new and great medical resources area on this site - also on the homepage - you will see a box that says Medical Resources....
Also - (am I overwhelming you yet?) look here for gatherings of the bpi community - this is a good way to get your little one looked at by a specialist (free, too)

It's also nice to go to the picnics to meet others as well - AND they are fun!
I hope and pray that your angel keeps on going forward and moving that sweet arm of hers more and more every day.
