Yup, learn acoustic guitar first, then electric. You will be a much better player for it.
Buy a decent acoustic. Do your research online then go and play with them ( I know you dont know how, but push down the strings, fumble and see how it feels, sits, etc). Don't be afraid to push around the salesperson (Guitar Center = bad) and make then take down many guitars and sit through your fumbling. You may be buying your first guitar, but that does not make you any less of a paying customer.
The best tip I have when it comes to playing is to wash your hands very well in quite warm water and dry them very well before you start practicing every time. It gets the blood flowing. The washing in warm water warms your hands up and betters your circulation, the soap cleans your hands, making the strings last MUCH LONGER and the drying sensitizes your hands and fingertips (painful for a while, but eventually helpful on electric) making your touch lighter.
