Yes, you can cut the flowers to encourage more bloom.
Most don't need to be trimmed or pinched unless you want the plants to be more compact, but I don't recommend it. You would have to stop by July 4th or your blooms will come too late.
Dahlias can't take any frost, so if you're in zone 5, you'll have to dig them up in the fall and store them for the winter.
Plant them in full sun and space them at least 24" apart. Hopefully there were labels that came with the plants. Do save those for information and the names. There are hundreds of different varieties of dahlias.
You can do a search at www.google.com using the full name in quotes. You can also click on 'Images' and often get pictures as well.
I'm enclosing a link that should be helpful with info.
