Wow. 'Hate' is such a strong word!
What you have are a couple of minor annoyances.
To get to the list, just press the left arrow button from live TV. It'll take you to the last place you were in the menu, usually the list.
As for the things you don't use, well, others DO use them, so it's not really bad to have them is it? Just ignore the TiVo Suggestions folder and turn them off in the settings, then delete everything in the folder and, there you go. No suggestions.
Personally, I have found times where there was nothing particular I wanted to watch and I found something interesting in the suggestions folder. It doesn't actually cost me anything to have it running in the background, so I don't even think about it.
Sure, there are inconveniences just as there are with any product, but I don't HATE any of them!
