I really like to use perfboards (mine have single pads in the middle and pads connected in pairs on the sides, that's the only type available in my location).
Is any strategy or software to optimal use them (with minimal point-to-point wires)? Any good tutorials on planning are greatly appriciated!
P.S. Unfortunatelly stripeboards are not available here.
Not that I know of. Don't get hung up on this. Just put all the parts so the interconnections are as short as possible. However at the sorts of frequency we play with here it matters little.

Where is here?
It is probably just a matter of finding an importer or ordering it directly from overseas yourself.

Is this good to have insulated wires on the face side connecting two distant points? Should this be keept minimal?

I'm from Ukraine, using perfboards is just simply cheaper than ordering stripeboards anywhere.
Yes insulated wire is always good. Like this project of mine:
Hey, that looks just like my construction method, real hackers don't make no stinkin PCBs, slows you down.
By the way I really recommend Radio Shack wire wrap wire for this kind of construction. It's white and the insulation strips off much easier then most other wire wrap wire I've used in the past. My spool says cat. no. 278-502, 30 awg Kynar wire, length 50 ft. Found mine on E-bay cheap.
Personally, I think wires on either side of the PCB is fine, as long as you keep track.
The only thing I can think of, which might be the down side of using wires on the copper side is that you may block access to other solder plates if you do not plan well enough and if you accidentally melt some insulation you could run into some hard to find or intermittent bugs... But if your project is not very complex or you are fine either way...
I use bare bus wire on the underside for nearly all ground connections. The I use insulated wire routed on top for any voltage lines. Make it easier running them on top because you can pass the ends of the wire into a hole right next to where the connection will be made. You can bend the ends of the wire over right on top of the connection spot and solder.
What about using bus on the solder side not only for ground, but for Vs too?
DustinB, what about connecting IC pins? For DIP-8 555 timer I need connect 2 and 6 pins. Which is better, use wire over the IC, or connect with wire on solder side? First option is easier to solder, second -- much compact
It's really up to you. Whatever you feel is the best way you can do it without running the risk of any shorts. You can still use insulated wire on the bottom if you need to make a couple connections. Like I said, the main thing is mitigate the risk of shorts. Whether it be wires possibly touching or the bottom of the board touching and bridging the connections. I don't think there's an exact science to it other than to try and not break anything.

I had to make a quick and dirty board about a month ago. It was 10:30 or so when I finished and needed it for the next day. It wasn't too large so I got the hot glue gun out and just coated all the tracks on the bottom side. It actually worked out pretty well.

That's great until you come to change it.
I use tinned copper wire (uninsulated) on both the top and bottom of boards only when there is no crossing of one wire over another. When you have to cross wires over then I always use insulated wire.
