Ramps have their uses.
They're much faster to get the car up and the underside accessible(for exhaust work, oil changes, anything else that isn't a 'wheels off' job).
Personally, I feel a bit safer with ramps.
A 6wheeled 'Garage creeper' mechanics trolley is a must in any home mechanic's arsenal if they don't have a lift. Laying on cardboard or an old piece of carpet gets old pretty fast.
Just the ease with which you slip under and back out makes them worth it.
For sockets, I would also get at least 10 and 13mm 'deep sockets' in 1/4 and 3/8. You'll need the 10mm on the battery bracket.
The large torque wrench should hit 250 or more Newtons. Can't remember what the hub nuts required now, but yeah...
I have two breaker bars, one 40cm, and one 1meter bar. The first time you try to remove a front hub nut you'll understand why.
Get a set of adaptors and short and long extenders for the sockets.
If you can get a set of torx sockets:
The exhaust on my M49(1.4i) is attached to the gearbox with a bolt that requires one of these.
A long version can be useful on the rear axle mounts. (must be a 'slim' one, though)
I have a full set of ratcheting spanners. (looks like regular spanners, but the closed end has a ratcheting mechanism), but if you get a 10, a 13, and possibly a 17... lovely things...
There are special 'brake line' spanners with a narrow gap, but that can wait until you decide to mess with brake lines.
You can never have too many LED worklights(rechargeables, so they can be moved around), a mirror on a stick(looks nearly like a selfie stick, but useful) and a flexible wand with a magnet on the end...
Oh, and if you can get it, a big box of black Nitrile gloves.
(The black ones are for chemicals, and are stronger than the usual blues. )
