I don't want to sound like a jerk, but my number 1 tip is to stop spending money now and do a heck of a lot more reading before you go any further.
The New to the Hobby forum is a great place to start reading, especially with this thread.

If you can, return the filstar and get your money back. You don't need it. It can be used to house some rock rubble or maybe some GAC or GFO later down the road, but IMHO, you don't want it full of filter material.
If you can't afford a sump right now, I'd consider buying a glass bit off of ebay and drill the tank now. Put in some bulkheads and cap them off. Then when you can afford a sump later on, it will already be drilled. For a sump, you could take advantage of Petco's $1/gallon sale or you could pick up a used tank for $20 or so. Drilling is easy and there's no need to pay someone to do it for you.
Rather than distilled water, you want to use RO/DI water. You don't know what you're getting with store bought distilled water. Just because it is safe for human consumption, that doesn't mean that it is safe for your aquarium.
You certainly don't NEED Reef Crystals. Many reefers, myself included, use plain old Instant Ocean. There are many brands of salt out there. Again, IMHO, you don't need any particular one to have a successful tank.
I really don't want to discourage you, but please do yourself a favor and keep reading before spending any more money that you don't need to spend.
Good luck and keep asking lots of questions.
