About the first question - this mean you have config file that sais to bring up eth0 on boot , but something is wrong with your card - what exactly happens we can discuss after getting more information about you hardware configuration and modules .
For about tha second question - it is possible your xfree config file to have wrong settings about the card and monitor , including the basic ones - vertical and horisontal refreshig .
The core command you can try is #xf86config and to build a new file by few easy steps .

We will need a bit more information to help you with your first question.

1) What make/model/chipset is your network card
2) If you issue the command "lsmod" as root[without quotes], what is the output?
3) If you log in from the console, and as root issue the command "ifconfig" [without quotes] What is the output?
4) Has this card previously worked under a different version of linux? If so, what version?

If you can answer these questions then it should help us to diagnose your problems further.

Switch to text mode.  It's Ctrl-Alt-F7 or Ctrl-Alt-F4 I always forget which.  You can look through /var/log/messages that might give some clues, or try something like /sbin/ifconfig eth0
If you haven't set up networking, eth0 isn't "brought up" by default.  And something like ifconfig eth0 netmask would do it.  

I think the X configuration is your main problem from the sounds of it.  You can try some different resolutions by holding Control and Alt and then pressing the + or - keys on the numeric keypad.  If you can find one that works, you can get in and fix X that way.  Otherwise, maybe rename your X configuration file (to XF86Config-4.stuffed for example), and run XF86Config to set it all up again.  
That's where you can re-configure your video card (as well as monitor, etc).  Be careful when specifying the vertical refresh rate of your monitor too, else you might damage it!

First, as root, do: ifconfig -a - if there is a eth0 then it's fine.
Then try: ping - see if it responds.
then: if there is eth0 present do: ifconfig eth0 up
and: ifconfig eth0
then: ping
If eth0 is not present do: cat /proc/pci and look for your network card. If it's there - it means it's physically installed. Then do lsmod - it should list the modules you have in your kernel. If you know which module works with your card do: modprobe MODULENAME. Then it should appear.
If you still have problems please repost with all the answers you get from Red Hat posted.
For your video problem I would look again: cat /proc/pci and look for your video card and then edit XF86Config. Also: dmesg |more may help you - it contains the log file of system boot up. Thanks!

to Dandanio,
     thanks alot for your help, i will accept your answer soon, because your comment was too simple and useful for me, but i need just to complete the configuration of the network configuration to browse through the LAN, the surprise that i can connect to the Internet through the LAN but i still can not browse through any other machines (Win2k machines) in the network.
my machine is the only Linux Red hat machine on the network.
please advice..
