Only dedicated track bikes come with fixie only hubs and no brake tracks or brake mounting holes. The felt tk2 for example, which was a particularly common track bike in the 1700-2000 dollar range, came with flip flop hub, rim brake style rims, and brake mounting holes front and rear. So it shouldn't be hard to find something.
As for the tools, especially with SS/Fixies, getting the tools can save you some hassles in the long term. Park is great, and probably most common for chain whip, lock ring tools, and freewheel removers. But you don't need to pay their price for everything. Their cable cutter is nice but over priced for what is a wire cable rope cutter, places like farm and tractor will sell you the same tool but half the cost. Mine is made in Japan and was half the price, just watch for the ones that are exactly like the pedros brand, the handle squeezes close enough to pinch the skin on your palm.
