First, Sun Electric. They have some incredible prices. I'm linking the page that should take you to grid-tie, stand alone, grid-tie with backup systems.

Some notes:
"Laminates" are solar panels without the frame and junction box. You can save a little bit by going the laminate route and making your own frames and doing the gluing/soldering to attach the junction boxes, but you don't save all that much.
The inverters in their packages are good quality brands as are the other parts I've been able to check.
They don't included mounting racks in their systems as "one size does not fit all", but they will work with you to figure out what you'll need. The other option is to build your own racks.
I haven't done business with these people, but I've seen other people say good things about them and when I checked their on line feedback it was pretty good. Apparently they do a lot of business through eBay. That's where I found most feedback. You should do your own due diligence.

These are good people. I've done business with them for 15 years or so and they've been helpful and delivered exactly what they promised each time.

I'd recommend getting a copy of their catalog. There should be some good info in it on system design.
They also have several articles on line.

Then, the 'mother load' - Home Power magazine.

You might want to visit your library and see if they have back issues. Thumb through a few and you'll likely see stories on grid-tie and off-grid systems aimed at people just getting started.
They also have good info on line.
This page might be a good place to start...
