the second doubt... i was thinking about /boot /home and /, in the
same partition, should i consider other design? a /boot with ext2 or
ext3 and a / with xfs?

What I would do:

	swap	1GB partition on each disk

md RAID1

/boot	ext2	100MB
rootfs	XFS	remainder of disk
home
...

i'm considering only one partition with swap and one partition with
raid1+xfs, what you think?

I wouldn't do it.  See above.

in a crash (power failure) i will have better rescure with only one
partition? or many partitions?

Having a separate /boot is always a good idea.

And truthfully, for a system of this caliber, you don't really gain
anything by using XFS, certainly not from a performance standpoint.  If
you were already an XFS user on large systems and it was simply your "go
to" filesystem, then using it on this system may make sense.  And if you
don't have a working UPS, you should definitely stay away from XFS.
Power failure shouldn't cause filesystem corruption, but it may well
corrupt or zero out files that are open for write but not written.  XFS
journals metadata, not data.
