Daily: pump up tire; usually right before riding... like shaving in the morning.
Other: I lube the chain when I hear it squeeking (I use ProLink), and when I have it up on the stand to lube, I take the opportunity to brush the caked dirt off.
As for the bike stand, I made my own with plywood, metal threaded pipe, and a clamp. About $30 all told at Home Depot. Search under "homemade bike stand" to see how to do this (I followed other's instructions). Not recommended if you have very lightweight road or mountain bikes made of carbon fiber or aluminum... but all three of my bikes are steel. You get a much more rugged and heavy (a good thing) bike stand this way, for very cheap.
