Question 1: I have been searching for information as to weather open solaris

Reason is so i can setup to read/write from either linux or solaris.
As is, i have only been user of linux for 12mths, so please excuse my ignorance.
OpenSolaris doesn't understand ext2/3 partition. It doesn't understart
extended partition scheme. It needs one primary partition and will
create it's own partition scheme there. Then it will create a filesystem
with either ufs or zfs.
On the other hand, Linux understands OpenSolaris partition scheme and
ufs file system. It can also be made to understand zfs through fuse.
Question 2: Will open solaris detect the other os (pclinuxos)?
Possibly yes. OpenSolaris will not detect it as a Linux but will ignore
it as an unknown partition.
That's precise - it will do nothing about it. That in particular means
that it doesn't _support_ it in any way either, in particular ...
At present i am dual booting from grub (pclinuxos 2008) and have windows xp as
the other os. I intend to install to the present ´c´drive (first slice), and
understand the bootloader (grub) will be overwritten.
OpenSolaris installs GRUB and it can be configured to boot a linux kernel.
... it means that you install OpenSolaris, you'll loose the ability to
boot a concurrently existing Linux installation.
"can be configured" isn't quite right - _you_ will have to configure
OpenSolaris grub _yourself_ to do this. You don't do it - you loose it.
It's not technically difficult, just append the Linux boot entries from
the Linux grub's /boot/grub/menu.lst to the one on the Solaris
installation.
Since you can't read/write any Linux filesystem from OpenSolaris out of
the box, it's a good idea to copy the Linux grub/menu.lst onto e.g. a
removeable medium (memory stick or such). After installing OpenSolaris and
booting into it the first time, use that to get the Linux grub config
appended to the Solaris one. On next reboot, you should get your grub menu
entries for Linux back.
OpenSolaris grub is perfectly capable of booting Linux; the other way
round is not true, Linux' grub can't deal with opensolaris (except by
chainloading).
