I agree with what's mentioned above, usually the larger the better for a beginner. Look into Innovative Marines Nuvo line of all in one Aquariums. They are a little on the pricey side but are well built and well designed systems. Fluval and biocube are also good options to look into.
A good test kit off the start is definitely the way to go as well. Red Sea makes a really good starter kit that will get you through your cycling and beyond. Definitely do your research, there is a great search function on the home page of this site you can dig around to see if your question has been asked before (Odds are it has been), and if not feel free to ask away on the appropriate forum

Bulk Reef Supply also has a HUGE video library that covers just about everything you could even think of asking as well. So check them out, there 52 Weeks of Reef Keeping series is a great place to start.
Oh and before I forget, welcome to R2R!!
