<human>: Can you give me the gist of the text in a nutshell?

This will be my first year paying taxes. I'm working as an independent consultant, so I have to do everything myself. I'm going to pay federal income tax quarterly estimated. I plan on doing that for state income as well, the snag there is that I'm a resident of Pennsylvania, but working in Ohio.
      
   Near as I can tell, I should pay state income to Ohio, but state unemployment to Pennsylvania. Anyone have any inkling as to whether or not that is a correct assessment?

 
   I also believe I do not have to pay FICA, but instead pay SECA. This should be 15.3% of my self-employed income. And this is applied to 92.35% of my net-earnings (so...income minus applicable deductions [which are...associated business expenses?]).
 

   Finally...what have I completely overlooked? I'm trying to crash educate myself on all of this and I can't find a concise resource.
<bot>: Bunch of specific tax questions that I can't figure out. Either looking for answers, or a nod in the right direction of another resource/forum.
