Go to Sports Authority and buy a set of RAM clubs for $150. Here's a good beginner's set: http://www.sportsauthority.com/produ...:referralID=NA
Or, you can go mid range and get some used Callaways at http://www.callawaygolfpreowned.com/
... in my experience, Callaways have the best forgiveness, but they're a bit pricey.
Also, I'd check local thrift stores like Arc or Goodwill, you can find some good stuff there.
At 5'10", standard length clubs should be fine for you... I'm 5'8" and I use standard length clubs - just a tad long, BUT I get by.
