A really useful method for setting goals is the
SMART model.
The criteria speak for themselves really. So your aforementioned goals fulfil Specific, Measurable, Relevant and Time-related. Whether they are Achievable is a more subjective measure - if you have never played poker before, or are playing microstakes then perhaps not.
I agree with The Imp and would caution setting financial targets. I used to set a goal of 30k hands per month, which I further reduced to 1000 a day, and further still to 1000 before lunch. Setting shorter term goals can help keep you motivated, as you goals are readily achievable and don't seem so daunting. So try to set a mixture of short- and long-term goals, and try to set goals that are more task-based then results based - although you will always need a sprinkling of results-based goals.
There is really lots of stuff on the internet about the SMART model - it's very easy to understand, and well-validated empirically.
