BART is the single largest provider of off-street parking in the USA. CalTrain seems to be trying to match it.
In New York, the commuter rail stations are surrounded by retail/residential. I live ~20 miles from Midtown in the suburbs, and I haven't driven my car in two months. I can go to the Costco, 27 miles from downtown, entirely on the train and walking (it's right next to the station).
In Chicago my wife would bring a rolling suitcase. You can also use something like this: http://www.walmart.com/ip/Whitmor-Rolling-Utility-Cart-Blue/....
We have these black rolling carts where I work for carrying around litigation documents. I'd imagine something like that would work too, and look less bag lady-ish.
Sunnyvale has a bunch of apartments near the CalTrain station that will come online this year so that will be interesting.
(Also the hardware industry has gone down significantly in the past 20 years. san jose will never have the 70's and 80's again)

i think the key is that outside of a couple of key stations in industrial areas (bridgeport, scott road and a few of the north burnaby stations) there is almost no street parking. the rail stations aren't sited and designed as collection points to funnel people downtown or to the airport. they were placed to encourage development of neighborhoods
