Rytsas, Naerys! It sounds like you have an interesting plan!
Right now, the valyrian learning aids are all under intense development. To get a 'leg up' on learning Valyrian 9especially High Valyrian), you might want to carefully study David Peterson's blog at
www.dothraki.com.
Keep an eye out here as well, as the wiki and now, the dictionaries are under active construction! Also note there is a section of this forum exclusively for Valyrian.
