I'm considering building my own drums out of maple tubing (there is a drum manufacturer here in the town I live and someone told me they often have scraps that I might be able to snag for free). Using the maple tubing would simply be for cosmetics and a "fun" project since the kit will only be used in conjunction with Megadrum, EZDrummer, and S2.2. I will also have silent mesh heads to appease the wife.

1. Do I need a bearing edge on the drums? It seems to me no, but I'd like an answer from you all.
2. What about lugs, since they are only mesh heads, are there head attachments that I could get by with that only have three lugs or do I need the six?
3. Thoughts on drum racks? Do I need to know the rack it's going on so I can pick the right mounts? Not being a drummer, this is any info you can pass on would be very helpful. I looked at drum racks and mounts and there are so many options. I want a physically stable kit without spending too much but leaving me open for expansion since I seem to have caught the DIY bug.
Thanks for your expert input.
