Hi guys, thanks for the quick reply.
Good that k30 will be about $300 cheaper. Can use the diff for another lens.

Well, I never used the ultra sonic cleaning part on my K5. I feel a simple blow w/ a strong blower is much more effective
. And no, it won't affect image quality.
For ultra wide lenses, you can go w/ DA12-24 or Sigma 10-20 or even the 8-16, or Tamron 10-24. All are good enough for general use.
For tele zoom lens, the DA55-300 would be a good start. The Tamron/Sigma 70-300 are pretty good too, but make sure you get the latest versions. If got money, go for DA*60-250.
If you don't know how to use an ND or CPL filter, can save it for later. People shoot w/o any ND or CPL filters all the time.
Dry Cabinet depends on your lens/camera collection. Are you gonna put in a lot effort (and money) into this hobby? If so, at least get a 100L one. You can use the extra space for other stuff like important documents/spare mobile phones/anything you can squeeze in. If just for casual shooting w/ a few lenses only, a 30L dry cabi would be good start. I don't think there is big difference between different brands, I myself use a DryCabi (120L) and a AIPO (135L). But I see people use other brands too.
You definitely need a good set of blower and lens cleaner. I'd suggest to go w/ the Gitzo Rocket blower, get the biggest one, cost 10 to 15 (at Cathay Photo or other shops). For lens cleaner, I always use Eclips lens cleanser and PacPad lens paper (available at Cathay Photo, Orient Photo and etc.). A bit exp, but well worth the cost imo. Can use them to clean sensors and focus screen too.
For camera bag, it's really just personal preference. I'd suggest to go w/ more comfy type like Crumpler 6 Million Dollar (good for one body w/ 3 lenses, or 2 lenses and a flash, plus lots of accessories). Can use dedicate tripod bag to carry the tripod if you don't carry it so often.
If you buy K-30, you probably already have some rechargeable AA batteries somewhere, can use those w/ an AA adapter (might get it FOC if you buy the camera from
pentaxwebstore). I'd go w/ AAs instead of another Li-Ion battery for K-30.
Flash can always buy later. You might need one or two fast SD card. I'd go w/ Sandisk Extreme 30MB/s type at least. Nowadays very cheap.
The best place to buy Pentax cameras and lenses would be the
PentaxWebstore
Cheers and happy shopping.
