Yep, like Mikey says, lots of us here own that family of mill.
After you've cleaned it up and got your adjustments right, the only thing you need is to build some confidence. Ignore some of what you may hear about round column issues, or at least don't let it bother you. These mills are capable of doing good work. Most of their minor design flaws can be corrected in the home shop. I've made a ton of chips with mine.
I am happy with a 5" vise, but it is the absolute maximum for that mill. A 4" is a better fit.
You should also consider a DRO setup sooner rather than later. I got mine from iGauging, which is hardly more sophisticated than HF digital calipers, but anything that fits will work. The power feed module is a godsend, cheaply available on eBay. With power feed and DRO, you're really waking up this mill's potential.
Then you'll need a drill chuck, a face mill or fly cutter, a R8 collet set, and of course cutting tools. Wait until you see the need for any tooling beyond that. There's a lot out there to buy, but try and hold off until you know that you need it. It will save you money.
