Hi @Anonymous ,
Sorry to hear you're having problems with drawings. By the sounds of your post, all of what you are wanting to do is possible as @jhackney1972 mentioned. I'd be more than happy to dig into this if you like. Feel free to email me at andrew.de.leon@autodesk.com and we can setup a time that works.
Just to answer your questions --
1. The contents of the parts list is defined by the properties of the components in your design. Its currently a one way street in terms of how we read in and populate parts lists (and bend tables). So to change a component's description for example, open the design, right click on the component within the browser and select Properties. Modify the Description, save the design and update the drawing. Help link: Parts lists, balloons, and bend identifiers
2. The columns displayed by the parts list include the basic properties. To change the columns and or re-order them, create a parts list and then double click on the parts list. In the dialog that appears you can add / remove / re-order columns. One thing to note here, the columns are limited to what's included in the component's properties dialog.

3. Balloons can be renumbered using the Renumber command which automatically updates the order of the parts list. You can also change the component a balloon points to in the canvas by using the manipulator that appears at the balloon's arrow when you single click a balloon.

4. The columns widths in any table including a parts list can be modified. Single click the parts list and you see manipulators along the header row. You'll also see a manipulator at the end of the parts list which allows wrapping of long tables.
5. Regarding your title block issue, its hard to say what's happening here without seeing it. The default ASME and ISO title block is standard compliant and fits in all sheets include the portrait A and A4 sheet sizes. If you're using a custom title block, it's all on you to get its sizing right. One thing to remember here is, the title block and sheet sizes are 1:1 and there's no option to scale the title block up/down as in other products. Best option is to create the title block at the size you want to see. If you need multiple sizes, you can create multiple title blocks and switch between them as needed.

Hope this help and looking forward to hearing from you.
Cheers, Andrew
