[SOLVED]Multiple Problems after a new install on Arch Linux

Question

Hello all,
I just finished installing Arch Linux from the core ISO which I downloaded from the site. The install went smoothly and booted up fine. Also I was able to install gnome and its extras fine as well. On the first boot after installing gnome I managed to get my resolution correct also. However later on after I installed compiz fusion everything with the resolution seems to be going wrong . My computer specs are shown below :
AMD 64 3200
Asus M2N MX-SE
2 GB Ram
Geforce 8600 GT
Viewsonic VA1918wm (Native resolution is 1440x900)
At the moment I can only manage to get upto 1024x768 and it looks quite bad at that resolution. I have attached the xorg.conf I have at the moment.

While I was trying to fix this I noticed I was encountering other problems also. For one I found that sometimes dhcpcd times out on booting up and I cant seemt o connect to the Internet on booting. Although I just thought of trying a static IP and I'll post if that helped later on.
Another problem is I found that I seem to get the following error randomly. Pressing ctrl + D after this just restarts the machine.
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Finally, while I boot up I noticed that it says "Mounting root partition as read only   [DONE]"  Is the root partition supposed ot be mounted as read only ? Attached my fstab just in case it is needed.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>

none /dev/shm tmpfs defaults 0 0

#/dev/dvd /media/dvd auto ro,user,noauto,unhide 0 0
#/dev/fd0 /media/fl auto user,noauto 0 0
/dev/sda3 /boot ext3 defaults 0 1
/dev/sdb1 / ext3 defaults 0 1
/dev/sdb2 swap swap defaults 0 0
/dev/sdb3 /home ext3 defaults 0 1
As you can see I'm quite new to Arch Linux so any help would be deeply appreciated.

Thank you for all your suggestions . I tried replacing the ID to Card0 but it didnt seem to fix it . However on the bright side I checked more threads on the forum and found some that helped out . :)

I copied the xorg.conf file from the third link and just made minor changes to it like removing all the resolutions I didn't need and now its working fine :).
Now Im just stuck with two problems. One is the following message which appears randomly.
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
******************* FILESYSTEM CHECK FAILED *************
* Please repair manually and reboot. Note that the root *
* filesystem is currently mounted read-only. To remount *
* it read-write type: mount -n -o remount,rw / *
* When you exit the mantenance shel the system will *
* reboot automatically. *
A thread about the same can be found http://bbs.archlinux.org/viewtopic.php?pid=295384 but there isn't a solution on it. 
The second is the intermittent problems with the Network being setup. Sometimes when I boot up it just says dhcpcd timedout and I won't be able to connect . However I can connect on another machine at the same time.
Took a look at the drive in question with gparted and it shows the below information:
/dev/sdb1 ext3   /   32.59 GB    4.92 GB   27.68 GB  boot
By any chance is any of the above information relevant :x ?
