You won't get a one-year ANYTHING at the Thai Consulate in Vientiane, except maybe a case of heartburn. If you are eligible for a extension of stay, no reason to go out of Thailand. Just go to Immigration with the required documents, and apply for a one year extension (marriage, retirement, employment).
If you're not qualified on one of the above basis, the best you can do is a double-entry Tourist visa (which Vientiane also will not give). Each entry is good for 60 days, and you can extend it at Immigration for another 30. If they give you 90 day validity, you can stretch it to 180 days, by leaving just before the 90 days expires, and getting another 60+30.
You may have to check around Thaivisa to see which Consulate is still giving double-entry Tourist visas.
Forget the shops at the border - they are a massive ripoff, and totally unnecessary. If you do go to the Consulate in Vientiane, there are many guys at the gate who will do the whole thing for you, so you don't have to wait in the sun, and they will check your paperwork, photocopy, make pictures, whatever - all for a price you negotiate. Up to you, but I think they serve a purpose, especially for a newbie.
