Since everyone seems to be in Beta I guess I will take a stab at this. The Stacker video is probably the closest thing to a tutorial you can find. There are a couple of stickies up top that have the basic info on what stacks and what their height is per item.
As far as the flickering the only suggestion I have is rotate the piece 180 degrees to see if it meshes better with that side. Or trying a similar piece of the same color palette. The smallest increment of placement seems to be around 1 foot so you can zig-zag things like you have done.
To stack I make extensive use of the oriental lamp and the floor tile for precise object height placement. That speeds things up much faster than stacking desks.

Sometime rotating 90 or 180 can help but in general the only way to eliminate the clipping flicker is to either alter the layout so there is no overlapping, or cover up the flickering area with something else.
Thanks for the advise. I guess i'll just have to try rotating it, and if that doesn't work, i'll just have to live with it 
A few days ago i stumbled upon a youtube video about someone who made a club inside his sg base. I was like
How is that possible!?
I then found another youtube video made by Stacker, who explained the wonders of stacking.
I decided to give it a go, and learn more while doing it. After creating things and come up with ideas for about 2 days, i managed to make my own club area. I'm pretty pleased with it, but i think there could still be much improvement.
One thing i came across is clipping/z-fighting. It seems to be pretty random. I've searched the forum and googled it, but so far i haven't found any solution. Is there even a solution? or is it just a matter of not having things overlapping each other? I've read that clipping could have a huge performance effect on pc's. Does this also count for hidden clipping? The walls of the building i'm showing below are made of two cabinets that are overlapping each other so the inside and outside wall have the same texture. Basically there is clipping on the topside of every cabinet but this is not visible because it goes all the way to the ceiling.

Is there a place where i could find tutorials on base building? And i mean something else than the basics of what a workshop is. I've seen some pictures in the thread at the top of this page, and i have simply no idea how people managed to do certain things.
