No you don't. You focus (manually) on where you're standing, set your aperture to something like f/16 or f/22, then rush back and use your remote trigger.donlim said:

infinity focus is focusing more to do with the distance between the camera and yourself as the subject. different lenses have different infinty focusing, most around 10 meters and beyond for SLRs.
steps to get your slr to achieve sharp focus across the picture (you need to stop down your lenses to get a huge depth of field) is to set your aperture to at least F8 to F11 for wide angle lenses. and f11 to f16 for others.
You need to use hyperfocusing, you don't necessarily need f/16-22 to get your surrounding sharp + subject 
Alternatively, is to focus at infinity, first switch the glass to manual mode, watch the infinity mark move on the focusing barrel till it hits the marking, then you're clear.

Let us get a few things straight.
You main objective is to do a self portrait right? Question: how far are you from the camera? If you are say 10 feet away from your camera, setting the lens to infinity focus will make you very out of focus! Infinity focus is focussing on "infinity", basically meaning something quite far away.
So forget about infinity focus for this project. Set your camera up. Focus using manual function. Use something to approximate where you will be standing/sitting. Then perhaps set your aperture to something like f16 to give yourself some room for error in focussing (assuming a focal length of something between 50-80mm). In my case, i trip the shutter and then run to the prefocussed place.
Will show a couple of images later when I sort out my computer. Seems to be acting up!

what type of focal lens u using ??
OK, here are the images. Something like these?
That is ME, of course!
When I was younger and trying to act like Tom Cruise!
(BTW, this was where that whatever you call movie starring Tom Cruise was made)
And when I was a "little" more mature and less inclined to play hero!:cry:
