Cool thread since it's something I've read a lot about.

Will this affect regular people at all?

I don't know but since a lot of Russian people want Putin to invade Ukraine then it must not be having a huge effect.

Has it affected any politicians (assume that would only bite them if they have assets abroad...)

If it does then they don't seem to care. The Russian parliament wanted the West to sanction all of them and there's a popular saying in Russia right now: "Добавь себя в «чёрный список» США.". (Add yourself to the blacklist of the United States."
They have an online petition for that and it's viral.

What long term effects will the sanctions have...

Imo, the long term effects will strengthen Russia and the eastern Trade Union. But it will also be devastating to the US and EU economies since the 5th largest economy will exist almost entirely in the east. And I don't see the TPP competing with that.
President Putin has already signed an agreement with Belarus and Kazakhstan, signed an agreement with China to double Russia's gas and oil trade with them, and signed an agreement in North Korea to construct new pipelines. Russia probably has enough options to make the Western sanctions irrelevant to Russian prosperity.

Will this change Russias stand on issues relating to Ukraine?

Русские не сдаются. President Putin said at the meeting in Germany that the sanctions will have no effect on Russian policy. Russia's stands on the issues will never be changed by sanctions.

Sanctions are like NGO's. They are used like weapons to attack other countries and force them to change to Western standards. Only weak nations cave in but Russia is not weak.
Btw, I think it's illegal to interfere with satellite signals. So even if the West attacks RT, people will still be able to receive the signal with satellite dishes. We have 2 dishes and we get RT on TV, on our PC's, and on the radio.
