Home page edit

Hello, firstly i must say that I am a real beginner in wordpress. This is my first work on my own web pages. I chose theme Fotografie pro. I set my home page as not static, I mean i want the newest posts could be displayed. I need to get the same function as in the oficial demo Fotografie pro - I mean when you clic on HOME (in menu) or FOTOGRAFIE (title), you will get the same homepage. I have created the page HOME (in my language Hlavní strana), but It is single empty page - how can I link it with homepage? My second question is, how can I change the font (size, color...) in homepage (in demo "NEWS"). Thank you
