I don't think you'll be able to get a decent board and bindings in a local shop for under $300. Personally, I'd look at spending about $200 on a board and $100 on bindings. Buy 09/10 stock online. Then when you buy your boots locally, ask them to help mount your bindings. It's not hard, but you'll have more peace of mind if someone shows you what you're doing.
Also, if you have an ebay account and have had one for at least 6 months, ebay is giving 20% back on your first purchase when you sign up for Bill Me Later (only good through the end of the month - a few more days). If you can find a board you want on there, that'll make your budget go a lot further.
