I'm not quite sure, as it's been a long time since I used eu2toRev, but I think your civilized status depends solely on your tech levels. Basically, you have to stay competitive in eu2 and then you'll be good in Vicky, too.
Manufactories will convert to factories at a decent rate, but you'll probably want to make sure you don't have all arms & naval ones as they are unprofitable in Vicky at the beginning. Level 5 forts will convert to Lvl 1 forts in Vicky. Military units will convert. Not sure about artillery, but infantry and cavalry work fine. You don't have to separate them. Ships also convert.
Not sure how culture conversion works. I guess your stuck with your primary culture. Pops are created from your population, so it's better to own a couple of highly populated province than vast stretches of wilderness.
On the whole it's important to stay a medium power in eu2. A small highly developed Ethiopia is a nice challenge in Vicky, a Russia spanning the half of Europe isn't. I think you have the right idea there.
