Re: linux partition extend
Tools like parted/gparted can do that for you - there's even a live CD with gparted on their site.

Re: linux partition extend
Filesystem extension is not at all tied to LVM: if you can first extend the underlying storage unit (be it a partition, a LV or a LUN in a SAN with no partitioning at all), then you can use the filesystem resizing tools to extend it.
A traditional partition can be extended only if the partition and free disk space are contiguous on disk; this makes it much less flexible than LVM. But it sounds like this might not be a problem in your case. (Seeing the output of "fdisk -l /dev/sda" would help in verifying this.)
Extending a traditional partition will often require unmounting it, because partition table changes can take effect only when the partitions are unmounted. On a system disk, you may have to reboot to make the partition changes effective.
On RHEL 5, the "partprobe" command can make (some?) partition table changes effective while a disk still has some partitions mounted; I'm not sure about RHEL 4.

Re: linux partition extend
Sure you can - in fact, even if you have LVM, it only does part of the job.
The other part is handled by filesystem specific tools/libraries, i.e. resize2fs and the likes.
