bondoman,
Thanks for the advice.
At this stage of the game I'm only doing research but I do know what you are talking about. You and others (jtilley comes to mind) have suggested only getting the parts you need for a few weeks of work at a time. Good advice I'm sure. As I stated in my original post, I have Revell's 1/96 Cutty Sark to do first. I am still researching her a little but there's a lot more information on her from a modelers perspective to be found on the internet than there is on the Preussen.
As far as losing interest goes, I'm sure I will stop working on whatever model I have on the bench for a couple weeks at a time here and there - and work or play at something else for a while. That was my habit while building the Connie and I always came back to her after a short break.
RE: blocks for the Preussen. She was such an enormous sailing ship that I'm sure one might actually be able to squeeze in close to 1k's worth of blocks if one was that committed. I'm not sure it would enhance the build though. I'm convinced that, at 1/150 scale, one can build this model with far fewer blocks and still have a model that most observers, even other ship-building modelers, would consider to be a very accurate representation of the original.
I still don't know enough about rigging in general to know where to put blocks that I can't discern from Heller's rigging pages. I'm sure the little "blobs" on the rigging - which I assume to be blocks - are way too few. After all the Preussen hoisted 47 sails on 5 masts! There must have been lots of blocks for that running rigging but I will just have to rely (as of the moment) on what pictures I can find of her and what information I can glean from modeling sites on the 'net.
Here's an example of information on the Preussen I found on the Internet that may be helpful to me when I begin the project: http://jans-sajt.se/contents/Navigation/Modelling/R_Preussen.htm
I wish I could find more rigging images/plans.

I just found this page which, even though it represents 18th century ships, I believe will be helpful in the placement of some of the blocks. Here's the page:
