If you download the free program "Before You Know It" from www.byki.com and select Russian as your language to learn you will get several (actually a lot of !) word lists split into interactive flashcards. They will help you learn a lot of new words. They are arranged by topic (for example "Days of the Week", "Food", "Clothes" etc) My students use this tool and find it very useful.

maybe that could help you? http://www.artint.ru/projects/frqlist.php
