Does it have any planets revolving it? Do they have names? When were they discovered? etc. etc.

Since Sirius is only 8.6 light years away that would be a huge discovery and we would certainly have heard about it if it were to happen.
This is not to say that Sirius may not have planets. It may mean, for example, that it does but their discovery is escaping us because our instruments are not sensitive enough for that task.
Keep also in mind that Sirius is a binary system, with Sirius A being a spectral type A0/A1 star and Sirius B a white dwarf. That means that Sirius A is a fast spinning star while Sirius B a dead star.
So the chance for Sirius A to have planets around it is small because stars with planets spin slower, much like our Sun. Similarly, Sirius B having gone previously through a Red Giant phase may have 'swallowed' all planets around it, that is, if it ever had any. Notice also that binary stars do no favour planet formation.
Bottom line: we don't know for sure but probably Sirius does not have any planets for the reasons explained above.

Sirius is actually a double star - Sirius A and Sirius B. A third smaller companion has been theorized from the irregularities in the orbit of Sirius B but has not been confirmed yet. For more information on Sirius click on the following link:

No planets, but a companion star, Sirius B. It was discovered by accident in 1862. An American telescope maker by the name of Alvan Clark was testing a new lens when he discovered Sirius B. If it were alone in space, you could not see it from Earth with the naked eye, but a small pair of binoculars would reveal it. This makes it about as bright as the planet Neptune. However, it is lost in the glare of its brighter companion and you need a telescope to see it.

No planets orbiting Sirius have been detected.

To the best of my knowledge, no.
