My suggestion would be to start with a decent rod or two. Don't spend a ton of money to get the best. The reason is simple. There is no guarantee that fishing will be your cup of tea. Fishing is really no different than any other hobby. Folks think they'd like to do something, start out, and then lose interest. For others, a hobby becomes an obsession.
SirSnookalot's advice about starting out at a local tackle shop is on the money. They will know what works for the various species, and what works at different stages of the season.
The beauty of fishing is that each of us can do it our own way. We can go "by the book", or think outside the box like mad scientists. Each can approach it as seriously or casually as they want.
Good luck, and have fun.
