They work really well together. 
Your picks so far look solid to me, except that once you reach SO level of enhancement, you'll only need 2 recharges in Active Defense.
Get a few slots into Parry soon. Also, once you hit DOs, I like to have end reds in my attacks even at the expense of some damage.
You have two power picks open before your next critical power, Against All Odds. If you are getting travel powers, now might be the time. Otherwise starting Boxing & Tough with an eye toward Weave later is good, or Build Up and something else.
After AAO, I'd pick up Whirling Sword (it's not the best PBAoE, but it IS one, yay!) and then Phalanx Fighting (even if Weave is available at 20, get Phalanx first, it's passive with no end cost.)
Then you hit another stretch of two picks where you could get pool powers like Weave and Hasten, before Disembowel (it is both hard-hitting and offers some mitigation through knockup). Then 2 more "your choice" picks...although you eventually want Grant Cover, it doesn't have to be here; you could get the Medicine pool or fill in stuff you missed earlier.
Then Headsplitter and Shield Charge and, if you want it, One With The Shield (You can use it to mule the Steadfast 3% even if you don't like to click it). After that you're into your epic/ancillary!
If you slot and use Parry you will find this a very tough combo.

Hey all, I just made a new Broad Sword/Shield defense toon today, and I thought I'd get the forums advice because I'm not terribly familiar with these sets(or scrappers in general). I'm hoping to have a character who is fairly tough to kill and can handle being in large fights. I guess first is checking to make sure these sets work well together, and next is to see is my build is any good. Here is where I am right now.
