I'd say take a step back for a second, get the camera with kit lens AND an old manual focus 50/55mm. I suggest the M 50mm F/1.7 or K 55mm F/1.8.
Not only are these great lenses, but they will help you to learn about photography as you use them. Also they can be had for under $100
If you realize you want more reach than you can look into several cheap options to start with like a DA 55-300mm or if you become in love with primes like me an old 135mm/200mm (M series ones go for under $100 and are great).
If you realize your want something like you said around 30mm than again buy an old M/K 28mm F/2.8 or F/3.5.
Before buying all this expensive equipment I suggest buying some good old lenses and really get a feel for everything. Than you can sell or keep them when you think your ready and buy those beloved limited lenses or DA* zooms
They aren't going to magically make your images amazing though, so keep that in mind
