Configuring Gmail for Own Domain

I recently got accepted as a beta user for Gmail for own Domain. I have 2 Issues.

1) I tried configuring the MX records and I see the 404 Error page instead of the Gmail login page (before it used to be the Squirrel Mail login). I would like to know if I have done anything incorrectly for my account with the directions listed below. Is there a time lag for this configuration set up? (15 minutes have gone by)
2) I would like to configure IMAP support with a client like Outlook with use with the Gmail interface (which hasn't popped up yet...from item #1). The Gmail for the Domain comes with a built in POP3 support but I'd like to use Dreamhost's IMAP support if possible. Can someone explain how this can be done?

=========MX DIRECTIONS==========
Procedures for changing MX records vary greatly from ISP to ISP. The instructions here are meant only as a general guide.

1. Login to your ISP using the username and password associated with your domain.
2. Navigate to an MX record maintenance page. MX records are special DNS (Domain Name Service) records, and are often located under sections titled "DNS Management," "Mail Server Configuration," or "Name Server Management." You may need to turn on advanced settings to allow editing of these MX records.
3. Delete any existing MX records before entering new MX records.
4. For each MX record, enter information according to the entries in the following table.
You may not be allowed to enter the priority values exactly as they appear in the table below; in that case, simply ensure that the server addresses are prioritized in the same order as they appear in the table. (i.e. The priority ranking [1, 3, 3, 5, 5, 5, 5] should work just as well as [1, 5, 5, 10, 10, 10, 10] so long as you keep the addresses in the right order.)

If you're asked to specify the type of each record you're adding, enter "MX".

MX records often require the specific format of DNS records, including a trailing dot (".") at the end of any full-qualified domain names (e.g. "server.example.com.")

Set any TTL values to the maximum allowed.

MX Server address Priority
ASPMX.L.GOOGLE.COM. 1
ALT1.ASPMX.L.GOOGLE.COM. 5
ALT2.ASPMX.L.GOOGLE.COM. 5
ASPMX2.GOOGLEMAIL.COM. 10
ASPMX3.GOOGLEMAIL.COM. 10
ASPMX4.GOOGLEMAIL.COM. 10
ASPMX5.GOOGLEMAIL.COM. 10

1. Log in to your account at http://www.enom.com.
2. Click the domain name that you'd like to use with Gmail for your domain. The main domain name page will appear.
3. Under the DNS Settings (Zone File) panel, click Configure. The Domain Name Host Records page will appear.
4. Under the Mail Host Records Setup panel, replace any existing entries with entries according to the table below:

Note: Make sure each entry is entered exactly as it appears in the following table. Be sure to include the trailing dot at the end of each record.

ASPMX2.GOOGLEMAIL.COM. 40
ASPMX3.GOOGLEMAIL.COM. 50

After you change your MX records, it may take up to a day before we can detect the change. Sorry, but sometimes the Internet is slow... even for us.
