Just follow the stars in theMentz/Tempest guide and you should enjoy yourself.
I try and plan days to get the most stars, longest climbs with the least walking inbetween. Even the low grade routes can be fantasticly enjoyable and sometimes make you think.
I good day on the Right Watchtower Face is Panzer, followed by Mantle and then Brolga. That way the climbs progressively harder and hopefully you'll get dialled in.
I found Watchtower Crack a bit scary but a fantastic experience. Even with big cams the first few metres of pitch 4 are unprotected.
I thought Agent Orange was a little over rated at two stars.
A good combo is Kaiser pitch 1 followed by Resignation.
I always have great memories of Araps as having great, solid jugs and loads of pro but when I get back there it dissolves into polished bulgy rock with small slippy edges and fiddly pro...
Just be a little cautious of grade 15s at Araps. They seem to result in the most number of deaths.
