Hi Gilbert
Welcome. As Justin mentioned, an 8" reflector on a Dobsonian mount is a very good start. It would usually come with a 26mm eyepiece, thats ideal for most deep sky objects.
I'd also suggest a visit to your closest astro society, people are helpful and you get to see a variety of scopes before you decide yours.
You could also think of an 80mm refractor on an alt az mount as a grab n go scope.
Star charts, planispheres are all useful but you could also use the website calsky to look up what objects you could see at what time and where.
Stellarium is also very handy.
Let us know how you go and with questions, ask away.
