how easy is to reinstall Linux on SSD drive?

If you are going to install Debian, their site is probably the best and most detailed resource.

http://www.debian.org/releases/stable/i386/

As easy as it was to install initially. The install obviously varies with the experience/knowledge of the user. Installing to an SSD, an external USB drive is the same process. The thing you need to watch for if you have multiple drives is to make sure you install to the right one.

Which from 3 torrents there is the latest one with updates?

If I create a Swap partition during installation, can I after configure Debian not to use swap at all?

To exclude swap (in a simple way) just comment out the fstab entry for swap.

yes, but the partition will remain in place -- you could remove it and expand the partition next to it ointo the space but it's not guaranteed to be easy.

what is possible partition scheme for 60GB SSD disk?

It depends on how you use data. For me, a 15GB partition for a potential 2nd bootable install, 4GB swap (in case I want to suspend/hibernate a 2GB RAM machine to disk). Leaving about 40GB for the full linux install. Potential to split that in half for a clone / back up / undo recovery type thing, or split part of it off for /boot/ to play the safe game. Although I'm more likely to use it all as my primary install. If I didn't do media editing where the undo history of large data types results in a bloated /tmp, I would probably split the 40GB. But the workflow of that extra space has it's uses. Especially if you like trying out other distros in odd ways like through a chroot instead of virtualization. Or do future installs in odd ways like debootstrap + rsync after the fact to put it to where it will boot. So basically:

15GB == reserved for interest of the week.
5GB === swap (suspend / hibernate) or toss away for other interests.
40GB == the / of a linux install

But that's just my opinion, the initial 15GB is for the times that I've played with things like gentoo, I've tended to end up at about 12GB usage before I have a GUI that does anything. So if I wanted to toy around with other distros that's a reasonable size. My opinion of course and YMMV.
