As for tools, I'm assuming you have some basics like a set of screwdrivers and a pair of pliers. You probably don't need (many) SAE tools for this car. Go to Lowes or Sears and buy a nice set of 8-10 metric sockets, a socket wrench (not one of the silly palm ones, just a regular socket wrench; paying a bit extra for a fancy low-angle one is worth it IMO), a couple extensions, and a universal joint. You should be able to find this complete with a case at Lowes in their higher-end Kobalt brand for about $20. Don't spend $100+ on a huge box of stuff you will never use.
Also, a pair of mechanics gloves, ramps, oil drain pan, oil filter wrench, and a tire pressure gauge.
Beyond that, you will be buying tools for specific jobs (or borrowing from your friends/relatives) as you need them.
Consumable stuff - some old rags, disposable gloves, some kind of soap that is good for removing grease/oil like Fast Orange, penetrating oil like PB Blaster.
Oil change, air filter, checking tire pressure, topping off fluids, changing light bulbs, batteries, wiper blades, checking tire condition... That's all super basic DIY maintenance stuff. Beyond that is stuff like changing serpentine belts, spark plugs, brake pads, fluid changes (transmission, brake, coolant, etc.)... not too bad but it's good to have someone help you the first time. This is all maintenance, not repair; these items will eventually wear out and just need to be checked and replaced according to the schedule in the manual.
Gaskets, tie rods, fixing leaky brakes, replacing starters and alternators, are definitely DIYable for someone who has tackled the simpler stuff a few times and is comfortable working on cars, but if you aren't making a hobby out of working on cars, it's a good idea to let someone else do these things.
