Assuming you are using kraft faced batts, and a drywall ceiling, I'll add another pointer.  Dont staple the tabs on the bottom of the truss.  Staple them just around the corner on the sides of the bottom truss cord.  Otherwise the paper tabs are apt to cause 'nail pops' in the wallboard over time.  Plus if you plan on glueing it (as recommended on a ceiling) the glue is worthless if its on the paper.

If I understand you right.. staple the bats on the inside of the truss, not wrap it around the outside... correct?  So, cheapest is generally best because they are all pretty much the same.

Also,

Any pointers on truss ties?  My basic plan is to copy the truss system in our bedroom which covers a similar width (30 ft).  Is gluing advised if I'm using truss ties?  Don't see any evidence of it in the original but it's a good idea to figure out what will will give the best performance for the price / effort.  
Thanks again!

Right, leave the bottom 2-by surface exposed so that the sheetrock can be fastened to it directly.
They are pretty much the same between like products, just make sure you're not compairing apples to oranges.  

By truss ties I guessing you mean bracing the trusses together by fitting 2x blocks between them (bridging)?  (I know terminalogies vairies between regions) Mimicing your existing home construction is a good plan if its also pre-manufactured trusses.  Id recomend always glueing ceilings.  There are less problems with cracks and pops when the sheetrock is bonded to the framing, and "DSA" drywall adheasive is not that expensive.  IMO glueing walls are not as critical, but it is pretty common to see that in a job spec. also.
Ive litterally spent weeks at a time going through apartment units fixing drywall, and 90% of the problems wouldnt have happened if it had been glued.
