Can someone please tell me how to beat shadow queen... and also, can you..

Try get more HP and FP. Then take on the Shadow Queen. Use everything you have to beat her.

First off. 33 BP?! That's it? You must always have a lot of BP, so you can do really awesome movez!

Secondly, you should be fine for facing her down. It's not so much about your stats, it's about having at least 2-4 Ultra Rank partners, the right badges (Power Pluses and various damaging jump badges are always at the top of my list), but most important is to get a lot of good recovery items. Such as a lot of Whacka-Bumps (25hp+fp, and they're free-just hit that weather guy in keelhaul that comes out of the ground. You can only hit him 'bout 10 times, though).

Hope this helps! If not, level up like MAD!

Get a load of ultra shrooms, and jammin jellies. then giv em to taste t. to make a crap load of jelly ultras. equip all the FP, and HP up badges you possibly can.

Make sure you still have the piercing blow badge on, though, you'll need that, it helps A LOT.

Then after that, battle her startin with one partner(goombella pereferabbly, so you can tattle), then as one dies, just switch out to another till you're out, and if you still haven't beaten her, just battle her on your own.

Remember to use the supernova special attack first, though!!
