Hi, Jeremiah,
As you can see from the responses, your questions aren't simple at all. Allow me to suggest a book, “Essentials of Russian Grammar” by Maltzoff (http://www.amazon.com/Essentials-Russia ... 824&sr=1-1). It's a good beginning reference grammar and can address your questions about numbers.
I think you will find people unwilling to answer questions posed in Latin transliteration; that's partly due to the fact that there are many systems for transliterating Cyrillic in Latin characters, and it's almost impossible for people who are not English-speaking Russian professionals to determine what system you are using, or indeed if you are just using a haphazard system. Do set about learning the Cyrillic alphabet. It's much more sensibly used in Russian than the Latin alphabet is in English, and it will reward you fairly rapidly.
All the best, Don.
