In Repetier, you can use any baud rate, because the USB serial connection runs at full USB speed; the COM port is emulated. Mine is set at using 250000.
My cache size is set at 63, but it's OK to try 127.
My travel feed rate is set at 3000 mm/min (50mm/sec)
My Z axis feed rate is set at 300 mm/min (5mm/sec)
My manual extrusion speed is set at 1mm/sec (the box beside it is 20mm/sec)
My manual retraction speed is 30mm/sec
In Slic3r, it's normal to set the layer height to between 50% and 85% of your nozzle diameter. If I'm using a 0.4mm nozzle, I often use a layer height of 0.25mm, with the first layer 125% of that.
The number of perimeters just depends on how solid you want your part to be. Four perimeters is often a good choice.
Speed again depends on a number of factors; 50mm/sec is usually conservative. Some people routinely run much faster than that, but as you go to higher and higher speeds eventually you run into quality compromises or problems with the extruder jamming because it can't melt the plastic fast enough. It's material-dependent; elastic filament can't be extruded as fast as stiff filament. It's also dependent on your nozzle diameter and layer height. And quality issues can also be tweaked by adjusting acceleration settings.
