Nice to see some progress - What rocket families are they constructing pads for first? Angara? Soyuz?
Angara pad construction may start in 2015, once they have verified its operation in Plesetsk. Also, as per Anatoly Zak, in 20 years time even this baby may find a home in Vostochny:http://www.russianspaceweb.com/yenisei5.html
Report about the recent visit of Popovkin, along with few pictures:http://www.amur.info/news/2013/02/01/28.html

Based on those photos, I would say that there is a good chance that some launch pads are going to be built there within a few years.
- First launch from spaceport - in 2015 (Popovkin did not specify which LV, IMHO most likely Soyuz-2)
