Put simply, in a residential structure no light fixture you can buy in a commercial big box outlet is going to pose a problem.
Most residential circuits are 15A - some are 20A and some are 10A.
A 100W bulb on a 110V system uses just under 1A, so your light fixture would need to have a minimum of ten 100W bulbs to approach the threshhold for your house's circuits.
Plus you can get CFL bulbs which produce the same amount of light at a fraction of the wattage.
So - get what you like.
Before you start, make sure the power to the fixture is off (not just at the switch) and, if possible, confirm with a non-contact tester (a few bucks at a hardware store).
D are the screws that need to be put through B, which is the bracket that will be attached to the ceiling box to hold up the fixture.
To see which holes, align the bracket with the holes in the fixture base. Thread screws D through the back of the bracket so the threaded ends stick out front. Which side of the bracket is the back depends on the ceiling box and whether you need the offset on the bracket sticking down or up. (It often doesn't matter.)
C are the screws that hold the bracket B to the ceiling box. Once the bracket is installed, you can connect the wires on the fixture to the wires in the ceiling box (including the ground wire to the green screw on the bracket).
Place the fixture against the ceiling with the threaded ends of D sticking through the holes. Attach with the nuts E.
The threaded tube on A is screwed into the center of the fixture, the nut is then tightened down the tube to the fixture. The remaining parts are removed. After bulbs are installed, the globe is put on, followed by the soft washer, the hard washer and the next nut. Don't overtighten or you can crack the globe. Then the decorative cap is put on and then the ball finial.

1 - TURN OFF THE ELECTRICAL SUPPLY, preferably from the breaker, not just the switch.
Those two screws you see protruding from the box are there to hold up the light fixture. Extend these screws to their full length so that they are in the electrical box, but are as long as they can get.
Remove the glass and possibly the lightbulbs from the fixture. You should see two slotted keyhole spaces that should line up with the screws. Push the screws through the insulation and into the big parts of the holes. Rotate the fixture so the screws end up in the slots.
Tighten up the screws, but do not over-tighten. Just tight enough to snug up the fixture to the ceiling.
Reinstall a light bulb, turn on the breaker and test the switch. If it doesn't work, then remove and check to make sure the wires are all attached correctly. They might have jiggled loose during this process.
Reinstall the glass.
There is no adhesive. Don't use any adhesive.
