You don't want to upgrade your Bootloader... In general, we prefer the older versions because they take up less space, and the new versions did not seem to give any benefit...
I recommend using build 20755 for the Apache right now, as the newer builds are not quite ready IMHO... (In a month or two, this might change. )
There are prebuilt "clean" ROMs available if you look hard enough around, but the kitchen is usually a better choice... You might want someone to send you their "selections" file so you don't have to guess...
