Partitions in RHEL 4.0

I posted this earlier in the wrong forum. I apologize for the cross-post. Am still needing some help. Thank you...
Hello. I hope this finds you well. I have downloaded a 30-day evaluation of AS 4.0 and am at the partitioning stage. I need to partition accordingly for Oracle 10g. Oracle has given me the specs but I need a few more details. If you could help me I would surely appreciate it. I have gone through all the documentation/knowledgebase and googled but could not find specific enough information. I hope I am no bother.
I have a 40GB HD, IGB RAM.
Following are the file system specs Oracle sent me:
root - mounted on / - size 2GB
usr - mounted on /usr - size 6GB
var - mounted on /var - size 1GB
tmp - mounted on /tmp - size 2GB
oracle - mounted on /oracle - size 24GB
swap - mounted on (did not specify) - size 2GB

1) Which of these should go in LVM and which should go in Hard Drives?

2) When I tried to create root i got the following error> could not allocate requested partitions: Partitioning failed. Why is that?

3) Should any of the partitions in the above Oracle specs be Primary partitions?

Again, any help is surely appreciated. Thank you for your time and knowledge. Best regards... Addison

Hi addison, Can you specify the type of partitions you have created so far (primary or extended)
because

could not allocate requested partitions: Partitioning failed

this error may be due to the fact that there may be already 4 primary partitions on your hard disk.
just check it,

Hi Juneaid,
I am doing a clean install and using the disk druid.
It has the following listed before I do anything:
LVM Volume groups
VolGroup00 size-38016
LogVol01 type-swap size-1984
LogVol02 type-ext3 size-35968

Hard Drives
/dev/sda
/dev/sda1 type-ext3 size-102
/dev/sda2 mount point-VolGroup00 type-LVM PV size-38045

Thank you...
