64-bit Kernel and Extensions: No in 10.7.1
I have used the arch =x86_64 at
boot and it booted into 64 bit mode.
please can any of you tell me in basic step by step how to make it boot into 64bit every time without adding argument at boot?
thanks
again..

-Open your org.chameleon.boot.plist (usually in /Extra folder).
-Back up your original org.chameleon.boot.plist to some place you want.
-Open org.chameleon.boot.plist with text editor.
and Remove these strings only:
<key>arch</key>
<string>i386</string>
-then save and reboot your machine and you are in 64.

How can I check my drivers to see if my machine is able to boot with a 64 bit kernel, other than just trying and failing?

at the boot loader press space bar and a command line opens type
arch=x86_64

then press enter..and let your system boot up

Yes you can exactly check it by this method. And do -v at the same time then you can see if you have unsupported drivers as well. If something goes wrong restart your pc and it will boot in 32bit mode again.
