Now that I've experienced festivals I can provide some answers from my observations:
The festivities seem to last for two weeks. The first week is "unofficial" with just lots of stalls set up along the main road along the river (Quai Fangum). The second week these festivities seem to become "official" as most of the stalls are now fully operational but the size of the crowds are still limited. The last two days are actually two separate festivals.
The date of the festival is dependant on the date of the end of "Buddhist Lent", which is the first of the actual festival, taking place on the penultimate day of festivities. In 2013 this was October 19.
By 9am on this penultimate day there are minor boat races, west along the river from the centre of down since the river nearest the centre of town is not suitable. These boats were shorter in length and not much crowd was gathered.
After sunset on this day the "End of Buddhist Lent" festival consists of locals floating decorate rafts made of flowers and sometimes model boats, carrying small candles and I think also incense sticks down the river. Young sons of families typically swam a few metres into the river to release them.
The last day of festivities is the day after "Buddhist Lent" and this day is the actual "Boat Racing Festival" day. In 2013 it fell on October 20.
A local told me the boat races on this final day are at 1pm. Again west along the river in the same location as the previous day. This time all the boats were very long with many rowers and the crowds were very large. I watched about four races and I don't think there were any before 1pm. I then took shelter from the sun and heat so I'm not sure what time the "final" took place or what accompanied this.

According to sakunavoyage and tourismlaos, the big racing day will be on the 20th of October, 2013. The week that precedes the racing day is more of social activities (what you are experiencing now) as mentioned in tourismlaos:
One week before the race, Fa Ngum Quai (along Fa Ngum Road) is taken over by stalls selling all kinds of goods and foods or games, and loud music is played all day and late into the night
