For my next brew day, which wil be in a couple of weeks I'm going to to the following....
-clean vessels with oxyclean (we sell it at work).
-use sanitizing solution in airlock.
-get a two chamber air lock for secondary(so no sanitizer gets sucked back into vessel, just incase) or solid bung.
-replace all plastic parts.
-make an immersion chiller to cool wort faster(we sell soft copper at work).
-make my batch bigger to limit head space.
-and purge vessel with co2 before transfer.

This sounds like a lot, but it really isnt. I wish I could have a separate fridge for cold storage and more kegs, but space is an issue. I'm really excited to try these suggestions. If any one has any others I'm open to here them, otherwise, thank you everbody. This was a great first experience on a forum for brewing.
Just make sure you leave enough headspace during primary fermentation - otherwise you'll end up with a giant mess. It's just the secondary where you need to match the size of your vessel with the volume of beer. I brew 4 gallon batches and, if I use a secondary, I rack to a 3 gallon glass carboy. Headspace is practically non-existent and suck back is not possible.

Sounds like a good plan.

Definitely, My primary is 6.5 gallon and my secondary is 5.

Chandler, this is the old "wine into vinegar" conversion, but with beer instead. I don't know if that was the reaction that happened in my case, but it definitely involved oxygen (I knew I was incorporating O2 since I didn't have CO2 to purge the secondary), and I knew the temp of secondary was too high, since I don't have a lagering fridge (yet). The resource was Google, and I stumbled on a website explaining the conditions for the reaction, and it sounded plausible that my conditions were perfect. It was so severe with one batch (I forgot I left it in secondary) that I had to dump the entire thing. A few times I noticed the really small bubbles after I transferred to secondary, immediately siphoned to keg, and drank the beer with a slight off taste. Now I only do primaries and straight to keg, and don't get any of this effect/flavor. I will soon have a lagering chamber and will go back to secondaries the right way...

Hope this helps.
