Help with Google Apps / DNS Settings?

Ok this is how my current DNS is set up:

It’s the default settings for google apps, now I want to be to use my hosting and be able to use the google apps side of things for mail. Is this possible?

My domain support told me this:
“Now you will need to add the “A” records that are provided by your
web host provider. Two “A” records are needed, the first will
correspond to ”*.yourdomain.com” and it will point to the IP address
provided by your web host provider. The second will correspond to ”
.yourdomain.com” and will point to the same IP address as the previous
“A” record.”

But that doesn’t really make sense to me, my nameservers are NS11.ETHII.COM and NS12.ETHII.COM

Any help?
