I agree with most of the initial points (even if they were made a LONG time ago ;)
Disagree slightly with the JJs, I don't like them in general. My rule for tubes would be shoot a mail to Dougstubes and follow his recommendation. Usually he is spot on as long as he knows what you have and what you want.
For cables, I haven't tried the cleartone, but I can throw in two more good value choices:
-Mogami 2524 and make your own with Neutrik jacks - great great cable and used by many pros, and it's relatively cheap
-Sommer cable (Thomann) -> great quality though abit sturdy at times.
