truss analysis
(OP)
I need to design a truss which will bear a distributed load and be laterally braced. I can go thru a hand analysis by the method of joints, but since I'll have several truss lengths to consider this may take a long time. Is there any software available to make the task a little easier?

If wood - call your local truss supplier and they will do it quite quickly.
If steel, RISA or any of the structural software will do a nice job.

Deflection though is considerably more difficult.
RE: truss analysis
Deflections are a bit more difficult if you want great precision, but simple beam formulae using the moment of inertia of the chords will provide a value which, when increased by a factor of 1.1 to account for deflection due to web members, should be accurate enough for most purposes.

But when the power goes off, I can still solve the problem, using a candle. My electric eraser just won't work, but then again, I rarely need that anyway.

You probably don't need a curser either.

Never told him I just copied it out of a book.
Only thing I learned in college - how to find the information and how to read it.

Method of sections works best for this problem.

Timing has a lot to do with the outcome of a rain dance.
RE: truss analysis
All good advice from experienced truss designers. Be aware that all three manual methods mentioned assume pins at the truss nodes and will give axial forces only. You need to combine those axial forces with any chord bending.
