need advice for necessary setting

Dear Guys, i was assigned to be a photographer to High School 35th Anniversary I ask any of your good advice about kind of setting I need to use on my Canon 70D camera / 18-135 lens / 50mm lens / 320EX function will be done at night time...

thanks for your help!

All indoor under florescent light? 

I'd bring:

1. Bounce cards
2. fastest glass you have
3. Possibly rent 85mm
4.  Flash diffuser of some sort
5.  A flash bracket to get the flash away from your camera 

I mean the best setting for my Canon 70D...

For events like that, when I'm moving around often, I'll use aperture priority. 

You need to know how to set your camera and adjust settings as needed to be able to do an assignment like this. It depends on the venue, I've been in some that the lighting may be darker or brighter in some parts of the room.

You could go early or ahead of time and do some test shots but I don't think someone can tell you exactly how to set it without being there. It seems like you need to develop skills at using your camera in a variety of situations before trying something like this.

Forget the 50mm.
First when you shoot these are you planning on strictly in Jpeg, or will you be shooting in RAW format? With either one I personally set my White Balance under the lighting being used, it cuts down on one step in processing. This is because also I bet there will be some group shots where your flash will not be all that effective. This though depends on where the event is being held, as to whether you need it at all.
Second I would set my ISO range to as high as you can go with it without going into the Hi1, or Hi2 modes, or the pushes. This way you can get some good shutter speeds at various apertures. So set the ISO first at a speed that still gives you good photos.
Third shoot in Shutter Priority, and set it to maybe 1/125 minimum, with your 19-135 lens 1/250 would be better if there is enough light there. Also I am not sure but if you do have to use the flash 1/250 is the fastest it will go, though I do not shoot with a Canon.
The reason I said to forget the 50mm is that the 18-135 gives you a wide range, so you can compose on the fly. If you are using both you will be changing lenses all night. So using one lens makes it easier. Personally I would rent a nice semi wide to normal zoom with a lower f-stop.
I hate it for you that you got volunteered to be the event photographer. Also I am sure someone else will chime in. Because I know I am missing something.
But it would help us more if you could let us know what the place is like where the event is. Does it have high ceilings, or low one? Or is it outdoors on a poorly lit pavilion? This all makes a difference in how you attack the problem.

Oh dear.  I hope you have plenty of time for practice -

 I was thinking the same thing

Last year, I was the unofficial photographer for my 50th HS reunion. I used my 70D with my 18-200 IS (kit from my 60D). I shot shutter priority at /1200 using a Canon Speedlight with a diffuser (or bounced off lower ceilings). Had almost no unusable shots and a fair number of rather good ones.
I did some "practice shots" in the various venues to test WB settings since the light was mixed.

^^^^ THIS ^^^^

Before accepting an assignment like this you should have a clear understanding of the basics of photography and your camera.

Light is everything! You need to understand exposure, how your f stops and aperture correspond with each other. This knowledge is fundamental to photography.

You could try the "P" for professional setting....
