Most of what remains in the thread after the cleansing makes sense.
Did you thoroughly read the SP pages for Hood, Whitney, and Shasta, especially the sections on when to climb? There are links to message boards and/or current conditions as well. Are you familiar with typical, stormy Sierra and Cascade February and March weather patterns? It seems like you could do more research on your own.
Regarding Mount Diablo, and regarding TinOmen and I reminiscing (some deleted), that stuff was off-topic/not directed at you.
Mattski (deleted from thread) mostly trolls/makes comments that are not generally helpful to inexperienced members.
For Yosemite, having to use tire chains is unlikely (but you are supposed to carry them and could need them at all places mentioned in this thread during winter/spring if you time your trip poorly). You are correct that finding a peak hike there that is short, easy, high-altitude, and lacking a possible need for snowshoes is not likely in February, but you could have lots of fun near Badger Pass winter sports area (not far from Fresno) and could probably find places to use crampons near there or from longish hikes starting in Yosemite Valley. Snowshoes likely can be rented at Badger Pass. YNP and Lassen NP probably offer free/cheap snowshoe ranger guided hikes.
From Fresno, look up Huntington Lake/HWY 168 and then look up Kaiser Peak and Chinese Peak (ski resort on part of it) on SP. Also look up Lodgepole Logistical Center (Sequoia NP), Alta Peak, and Jennie Lakes Wilderness http://www.summitpost.org/jennie-lakes-wilderness/441944
. Snowshoes will likely be helpful.
As far as CA14ers in winter/spring, you need much more experience, but might progress quickly by paying for classes and guides if highly motivated and equipped. Seriously, I wouldn't even suggest trying in summer/fall without doing shorter hikes first and practicing more between 8,000-13,000 feet. White Mountain Peak and Mt. Langley would be 14ers to try in summer without the Whitney permit hassles and crowds. Whitney would be next easiest, but is overused due to being the highpoint of the lower 48. Mt. Shasta may work well in May/June (check webpage for conditions).
Also, I pointed out (as did others) in your Dana thread that higher does not equate to better in many cases. Keep in mind that you can't view the famous peaks very well while on them. As you gain experience and research more on SP, you will find great places that most people have never heard of aside from avid hikers and mountaineers. You will likely have more fun and enjoy better scenery on peaks that are not famous highpoints your friends suggest or have heard of.
Mt. Hood: see how your practice goes, consider guides, and be wary of likely poor weather/conditions. Your March goal would not likely happen safely and why go all the way there with so much in Tahoe area and Mt. Shasta closer. If you go, May/June would likely be would be wiser and simpler.
Tahoe area Peaks and Brokeoff (Lasssen NP): I'm not sure if you looked up the good suggestions listed by mrchad9 and others, but see why you would be confused/frustrated by the off-topic posts (much deleted).
Castle Peak/Lake by Mt. Shasta: lower than you are looking for, but be cautious taking on more than this in winter without more experience. Great views of Shasta can be had, and a range of hikes exist in the area.
Mt. Shasta would be a good place to practice skills in spring or sooner if you check conditions pages and don't expect to summit. Consider guides & classes.
Mt. Dana would be a longer drive and hike than you are looking for in winter. I think I recall Clouds Rest from Tenaya Lake area/Sunrise TH in summer sounding like a long hike to you, which would be easier than most ideas discussed in this thread. I will echo comments from others that you sound like you need more experience
doing long hikes in snow and long hikes above 9,000 feet in summer before trying more challenging winter/spring hikes without guides. What is the rush to try state highpoints?
I am considering all of these areas (excepting Whitney, Dana, and Hood) in the near future if I don't go to Death Valley instead. I may be able to provide conditions updates or see you out there.
This was good advice, although all previously suggested and an important point made:
Vitaly gave you a list. How will you do a snow hike and not use snow shoes if conditions are soft?
Shasta is easy approach and a good place to experience snow travel into summer.
Round top? Seems to be the yearly SP gathering spothttp://www.summitpost.org/round-top/15050
For summer, or other winter ideas, look up mrchad9's California's Fifty Finest list, or pick another interesting peak. After picking a peak, click on Interactive Map to see other peaks in the given area.
