Hi CC
Here's my two bobs worth:
Camera body
The 40D is a good body, but as EchiDna (and others) pointed out, you may want to consider a full size sensor instead (i.e. the 5D).   Both bodies will depreciate rapidly over the next few years, although the 5D is likely to hold its value for longer as new models will be less frequent. It will allow you to invest in full frame sensor glass right away, and the bigger image = bigger pixel size = more light / pixel = less noise/greater sensitivity.
If you have a budget in mind and can't fit the 5D, I'd  spend my money on quality glass first, and use what's left over to purchase a body (20D and 30D are dime a dozen and are also great bodies - upgrade to a 5D when the money becomes available).  Looked after properly, quality glass will last you a lifetime.  
Notes on choice of glass 
IS is nice, if you can afford it and if you're going to use it.  IS gives you 2 f-stops (or even 3) over non-IS ... but ONLY IF YOU'RE HAND-HOLDING!  
On a tripod it is neither desirable nor required! You'd turn IS off on a tripod, as it actually CREATES vibration by amplifying signal noise.  So if you're not using IS, its extra weight you don't need to carry and its additional complexity to break down later (

 think Isuzu county Vs P38A 

), never mind the extra $1000 you shelled out for it! 

 (Use it instead to upgrade to the 5D)
From what I've read of your post, it doesn't sound like you don't need it. 
As for your glass list, do you need / will you use all of them?
Considering the amount of money you're looking at spending, I'd recommend the following kit that gives you full range at the best speed / quality:
Canon EF 16-35 f/2.8L
Canon EF 24-70 f/2.8L
Canon EF 70-200 f/2.8L (non IS)
Canon EF 1.4 teleconverter (you may want to consder non Canon brands - Kenko do a 1.4 and 2 x teleconverters that are hard to fault at less than 1/2 the price).  
The above should set you back approx $5200. If you go with Kenko teleconverters, you should be able to get both a 1.4x and a 2x for the price of Canon's 1.4x.  This would give you the entire range you've had in your kit with better glass quality and the same (or better) speed.  
The other advantage of the above kit is you'll be able to share filters accross all lenses (all 77mm).  Circular polariser is probably first on the list (after 3 x UV filters for glass protection) followed by natural density (ND) filters and/or graduated ND filter.  Everything else you can apply in photoshop.
I'd invest the difference into the 5D upgrade. 
Lastly, notes on camera shopping in HK, know what price you expect to pay, and go to 10 different stores haggling it down further every time.
As a rough guide, look at what the cheapest equivalents are selling for out of HK on eBay, and expect to pay about 10% less.  Only a handful of camera outlets specialise in high end gear (the type you're looking for) know where your shops are before you get there.  I went to 7 different shops in 4 hours, with the list of gear I was after, and whatever quote I got at the last place, I took 3-5% off and said this is the XYZ quote, can you beat it, or should I keep going?
The line was OK, I've got 3 hours to get THIS gear (handing them the list) what can you do for me?  Oh, you sure?... cos XYZ offered me this much?... Can you beat it? (Dealer:earrrmmm...) Turn around and start walking away (making sure he can ambush you on the way out - helps if you get them to the front of the counter before faking the exit). Worked every time.
