Of course, there is a level of discretion here. If you are certain that you need the item, you need not fix it. But I recommend fixing all of the above.
You also have both AVG and avast! installed. You should never run two anti-virus software at the same time. Uninstall one and make sure it is done so thoroughly.
You might also want to uninstall Windows Live Writer if you are not using it.
From the looks of it, your browsing experience is slow because you simply have too many things going on. Toolbars, protection software, etc. On top of this the machine is not too powerful, so things start to slow down.
After all this, re-do a HijackThis log without fix, and then post the log again. Thanks.
