If I remember correctly, It does not come with the arm. The work rest platform is an accessory, too. The arm for the platen and the fork tip are the same. The arm costs $65. There is also a combo arm with a 5" serrated wheel ,a flat platen, and a 2" top wheel for $220. If you order it mounted on the unit (instead of a contact wheel), the arm will come with it. It is a very good starter arm.
The fork tip is an invaluable add on. You can get small wheels for it from 1/2" to 1.5". The 3/4" is most useful for finger grooves, and finishing the guard/handle junction. I have four or five arms with the most used platen/wheels mounted on them. It saves time, but at $65 each, changing the attachment as needed is certainly cheaper.
You will eventually want/need;
Contact wheel arm
Contact wheel ,start with a 3" and an 8" or 10" (Add more sizes as you grow)
Small wheel tip (fork tip) with 1/2 or 3/4" wheel. (Add others as needed)
Flat Platen (the combo head has this on it with a 5" wheel) Add a pyro-ceramic backing plate from Darren Ellis.
Work rest for flat platen. (I personally don't like one on the contact wheel)
Accessory arm (for platen and fork tip)
When you order your Bader, call the people you are ordering from and talk directly to them . They will know how to save you money in the features you get. The best thing you can do,if at all possible ,is get the variable speed unit.
It is also not a lot of dollars extra to order it with the 2HP motor.
If you haven't already done it ,you might want to give Steve at Bader a call directly. He will really work with you.
