Need assistance with DNS record changes

These are the resource records associated with my client's zone file.  Obviously, hosts their site and handles their mail delivery as well.  I made up the name "widget."

widget. org.                  NS             ns2. lowesthosting. com.
widget. org.                  NS             ns1. lowesthosting. com.
widget. org.                  NS             ns. widget. org.
widget. org.                  A             216. 40. 201. 201
help. widget. org.            A             216. 40. 201. 105
ns. widget. org.            A             216. 40. 201. 201
webmail. widget. org.      A             216. 40. 201. 201
mail. widget. org.            A             216. 40. 201. 201
ftp. widget. org.            CNAME             widget. org.
www. widget. org.            CNAME             widget. org.
widget. org.                  MX 10             mail. widget. org.

I want to take email delivery from and give it to Google Apps.  These are the MX and CNAME records that Google has instructed me to add:

Domain                  Priority            MX Server address
````````````````````````````````````````````````````````````````````````            10                  ASPMX.L.GOOGLE.COM.            20                  ALT1.ASPMX.L.GOOGLE.COM.            20                  ALT2.ASPMX.L.GOOGLE.COM.            30                  ASPMX2.GOOGLEMAIL.COM.            30                  ASPMX3.GOOGLEMAIL.COM.            30                  ASPMX4.GOOGLEMAIL.COM.            30                  ASPMX5.GOOGLEMAIL.COM.

Alias                               Type                     Server
````````````````````````````````````````````````````````````````````````            CNAME             ghs. google. com.
calendar. widget. org.    CNAME             ghs. google. com.
docs. widget. org.            CNAME             ghs. google. com.
sites. widget. org.            CNAME             ghs. google. com.

To make this work, I think I need to delete the following existing records.  Am I correct?
mail. widget. org.            A             216. 40. 201. 201
widget. org.                  MX 10             mail. widget. org.

I agree with collins23 :)

(To make it work properly anyway - you could have 2 MX10 records but mail delivery would then be shared between the original host and the ASPMX.L.GOOGLE.COM with the rest as backups.)

Yep, that's right. You only want the MX records referencing google's servers.

just my additional 2 cents:

I find aspmx.l and ALT1 and ALT2 heavily loaded at times, so I reversed which servers had the lowest preference. Just something to think about later on if you run into the same issue.            10                  ASPMX4.GOOGLEMAIL.COM.            20                  ASPMX5.GOOGLEMAIL.COM.            20                  ASPMX2.GOOGLEMAIL.COM.            30                  ASPMX3.GOOGLEMAIL.COM.            30                  ASPMX.L.GOOGLE.COM.            30                  ALT1.ASPMX.L.GOOGLE.COM.            30                  ALT2.ASPMX.L.GOOGLE.COM.

Thanks for the extra feedback.  

Thanks to everyone else.  I'm still new enough to DNS records that changing them makes me a little nervous.
