In regards to wanting to stick survey equipment on everything, I used to want to do this to, but really if you get the skill for it (it what? halves the cost i think?), and just put it on a couple of your larger ships, (or a few more smaller ones) it will be REALLY easy to get the equipment and supplies costs down to, or near the minimum 5 on almost anything but the largest normal planets, and gas giants. Hell, the first time I stacked it on everything I realised after I was Wasting op by putting survey on everything once i got the skill, because it was too much overkill. Now, I porbably wont put it on anything, I'll just take an Apoge(sp?) or two, that will lower survey costs, and the extra supplies I can take by bringing an Atlas or two will cover anything extra.
Hell, bring a couple salvage rigs and have the salvage skills, and you will return will more fuel and supplies than you left with if you want, and thats with surveying every planet along the way.
