As for the journal, edit your uo.cfg file with notepad. You need to add the following line in there. I have mine right above the dotted line part way down the list, under ClientLogin=
JournalSaveFile=c:\Journal.txt
Now you can change the location as it suits you. I actually save the file into a folder called UOJournal, so my line would look like:
JournalSaveFile=c:\UOJournal\Journal.txt
I wouldn't recommend using spaces, however. Not sure how Windows manages those.
Finally, make sure this line is set to On in the uo.cfg file:
SaveJournal=On
