Should I assume that you have been working out for a total of 8 weeks, and before that you had never worked out before?
May I ask why you feel that you're qualified to write your own routines and workout plans with such limited experience? Why not use a premade routine that is professionally written and takes the guesswork out of what you're trying to do...you'll get better results more quickly by doing so.
In general, the book "The New Rules of Lifting" is an excellent resource, but you can find free training programs at reputable websites such as t-nation.com too
