That doesn't sound like a bad start. I haven't heard them, but they seem well reviewed on the consumer sites. You're definitely better off spending your budget on those three now. Some matching bookshelves for surround won't be too hard to save up for later.
Another approach to making the decision without haste, would be to browse the forum(s) for the many "what speakers should I get for $$$" or "best tower speakers for $$$" threads. After wading through the remarks of people telling the original poster to read the countless other identical threads out there, you will get some good advice and opinions.
Don't be afraid to consider brands that you haven't heard of before. There are some pretty decent internet-only factory-direct places that compete on price and performance levels with some of the name recognition brands. KEF and Energy being two that I have not heard, but have seen mentioned in those types of threads.
Take the time to browse through the most recent 5 or 10 pages of topics in the
Speakers area to find some relevant threads, and you're bound to get some ideas.
Good luck to you.
