Hrm, IMO there is no reason to be using Model View 32 or PCS1, because PCS2 does everything those two can, and more. The latest version of PCS2 (or at least the one I have) doesn't crash at all - you must be using an outdated version, try updating. Should fix your crashing issues.
Also there is no use for table viewer 32, notepad(++) lets you view and edit at the same time. Not like tables are particularly difficult to navigate (I've never even heard of the program).
Ani builder is obsolete because you can have *.eff animations for just about everything, allowing for vastly superior quality (at the cost of effects folder cleanliness, but a small price to pay for having loss-less images for frames). There's no longer a need to be using *.ani files anymore, the SCP team has done some great work to move away from that terrible, terrible format.
What I use for my "one-man team" stuffs:
FRED 2 (Missions)
Notepad (Tables, Missions)
QuickVP (VP management)
Adobe Photoshop (Textures, Effects)
3D Studio Max + OpenCollada DAE plugin (Models)
PCS2 (Models)
Audacity (Sound Effects/Music)
Microsoft Visual Studio 2010 Express (Coding/Debugging) <- this one is absolutely necessary if you are working with SCP and using any "cutting edge" features, otherwise you will never debug anything
XFire (Recording Video - free, without any watermark/time limit, idk if this has changed though, haven't done any recording in ages)
Adobe Premier (Editing Video)
All one really needs
Notice the absence of Descent Manager Tools. They're obsolete. Made all of Dimensional Eclipse without the tools even installed, shows how useful they are nowadays. Community-developed tools and other advancements have really left them in the dust, relics of a bygone age of FS2 modding.
Photoshop easily replaced by GIMP
3D Studio Max easily replaced by Blender
Premier easily replaced by...actually I don't know, but there should be a free/open source option for video editing
