i realized the focus thingy, thats why i tryed all lab, greater overall output, numberwise.
i would love to read those how-to guides. maybe its just me, but i seem not to be able to use the search function, i rarely find anything relevant ;/.
keeping planets empty sounds like a good idea, dont know why i couldnt come with that... 
thanks again for the help 
edit: oh well i totally suck at the mixed approach. dont get any research done, economy is in the red and lots of trrop transports on their way while i have laser II ... 
edit2: i finally got a hold i a game. and its reeeaaallly fun. made a costum race with torian techtree, which i felt was best suited for an all fac strat. i wasnt so wrong. but i guess there are better choices. i had to step back to challenging. but its hard enough.
huge map all abundant with frequent mega events is just plain fun. those krynn nearly got to influence victory when i got an event(dunno if mega oder normal, doesnt really matter to me) where everyone gets a huge boost in their influece ability. i went from like 10% of the map to 30%. suddenly i could see myself on the map again
(i have to add that im colorblind[well not blind, dont know the english word when you have problems with contrast at boarders of two colored spheres]) then i payed everyone to start a war with them and suddenly they drop like flyes. their class 4 worlds just could hold up producing osmething worthwhile. then those dang drath declared war on me, one round later the dreadlords show up. the altarians and yor got a really bad start, the yor own just 3 system in two sectors, whereas i have like... dont know about 60-80 planets in 20 sectors or something. altarians only cover baout 4 sectors. and guess wo wipes out the dread lords, the altarians 
sorry if this is boring to you, i just had to point out how much fan that game is right now.
i have about 100 medium sized low level ships(a little bit better then the drath ones, the have more logistics though) all set on auto attack because i really hate micro. they dont have transports yet, so its not that risky. since i can pump out large sized ships now i guess i will take controllol of them to hunt the biggys.
i hope there will be morge events thogh. the spy event was really cool. suddenly i had 36(!!!) spys all over my little empire, i bet those kry got about 100 or even more. all the ai races tool that for an invitation and declared war agsinst each other. soooo much fun 
the odd economy boost event is helpfull too, even though sometimes i have to be careful with my treasury, nearing those 20k caps... most of the time i simply drop the taxes...
i have like double the population of the second most populous race(the krynn of course) because im a superbreeder with the highest pop grwoth bonus. i made the race resemble the morganites from alpha centauri. much they like money, so i figures they would like many tax payers 
well sorry for the spam, just thought id described whats going on right now
