Can I remove a Exchange server 2010 that I was trying to setup for migration and screwwed up my instal??? Help.

I am having many issues with the migration from 2003 exchange to 2010 exchange.  I have made so0me many different attempts to get the mail flow going in both directions I lost track.
I most recently removed both RGC using the command line and now I cannot get any thing to work except my outbound connection to the internet.  I was able to send mail to my gmail account.
Can I restart this installation?

First you should try removing the Exchange 2010 installation from Add/Remove programs.

If there are any uninstallation errors, feel free to post them here.

Depending on how badly the installation has failed, you may need to manually remove the Exchange Server.

If you started migrating mailboxes to the new server, you probably to move them back before uninstalling the new version of exchange.

Investigate before uninstalling or deleting. There may not be a way to backtrack if you don't have a backup.

Also: Have you taken a full backup before starting? if not, take one before proceeding.

I have been using this article, but somewhere i read something and removed my RGC (both side)completely from the Exchange 2010 box, so I tried to re-add them and I am now getting problems with email on my exchange 2003 server.
My SMTP routes are not working on the exchange 2003 server but are working outbound on the 2010 server...????

Did you followed the steps properly as I mentioned below:

1. Bring the Exchange organization to Exchange Native Mode.
2. Upgrade all Exchange Servers to Exchange Server 2003 Service Pack 2.
3. Bring the AD forest and domains to Windows Server 2003 Functional (or higher) levels.
4. Upgrade at least one Global Catalog domain controller in each AD site that will house Exchange Server to Windows Server 2003 SP2 or greater.
5. Prepare a Windows Server 2008 (RTM or R2) x64 edition server for the first Exchange 2010 server.
6. Install the AD LDIFDE tools on the new Exchange 2010 server (to upgrade the schema).
7. Install any necessary prerequisites (WWW for CAS server role).
8. Run setup on the Exchange 2010 server, upgrade the schema, and prepare the forest and domains. (Setup runs all in one step or separate at the command line.)
9. Install CAS server role servers and configure per 2010 design. Validate functionality.
10.Transfer OWA, ActiveSync, and Outlook Anywhere traffic to new CAS servers.
11.Install Hub Transport role and configure per 2010 design.
12.Transfer inbound and outbound mail traffic to the HT servers.
13.Install mailbox servers and configure Databases (DAG if needed).
14. Create public folder replicas on Exchange 2010 servers using pfmigrate.wsf script, AddReplicaToPFRecursive.ps1, or Exchange 2010 Public Folder tool.
15.Move mailboxes to Exchange Server 2010 using Move Mailbox Wizard or Power Shell.
16.Rehome the Offline Address Book (OAB) generation server to Exchange Server 2010.
17.1Rehome the public folder hierarchy on the new Exchange Server 2010 admin group.
18.Transfer all Public Folder Replicas to Exchange Server 2010 Public folder store(s).
19.Delete Public and Private Information Stores from Exchange 2003 server(s).
20.Delete Routing Group Connectors to Exchange Server 2003.
21.Delete Recipient Update Service agreements using ADS Edit.
22.Uninstall all Exchange 2003 servers.
