I'm doing an install of openbsd 4.8 on a desktop machine with 3 SATA

This is a multi-boot machine, so I don't want to install the bootloader
on the MBR, but would like to install it on the first slice/partition of
sd1.
In that case, should I choose to use the entire disk (previously home to
a linux install that I no longer want to use) and am I then able to
choose where to install the bootloader?
a bit vague...but no, you don't get to chose where "the" "boot loader" is.
The MBR goes where the MBR goes, the PBR goes where the PBR goes, and
/boot goes where /boot goes. They all go on the root disk, the disk
that holds your root file system, in your case, sd1. See FAQ 14.
If you want your machine to boot off an "alternate" drive, you need to
do some magic before the OpenBSD boot code (of all flavors) is invoked
to get it to load the MBR of the desired device.
Please read the FAQ section on multibooting (FAQ 4) over and over until
you realize this isn't trivial stuff.
