Earning my Class A's myself

I am in the process of earning my A's alone. I have my B's and the company I currently work for is going to let me borrow a tractor to do the skills test. I have been driving for 8 years. Once I get my Class A's here is the question. Do I consider myself with out any experiance when I talk to companys or do I bother mentioning the years of Class B driving. The only thing I have yet to learn is all my paper work ( inspection and driving log I think I have down pat, but not sure what else there is). I want to start running OTR now that my daughter is old enough to understand that I will be comming home. I am at a loss. The physical driving part doesn't worry me as much as the paper work and the experiance ( or lack of ) Any info anyone can give me would be great. I have been thinking about starting with a large company like Swift and then after a couple years looking at a smaller local carrier to finish out my career with. Thanks again for any info.
