Okay to answer your questions;
Each Planet moves at certain speeds and may at times appear to be moving faster or slower at any given time. If they are above their "mean" motion, they are considered swift, if they are below this mean motion, they are considered slow. Each Planet has its own mean motion. If you see in an ephemeris (its easier to use a computer program for this however since it is usually more exact) you see that a Planet has gone above its allotted degree allowance, you consider this quick in motion. The mean motions of the Planets are as follows;
Saturn - 3/4 Minutes a day
Jupiter - 4 minutes 59 seconds a day
Mars - 31 degrees 27 minutes a day
Sol - 57 minutes 15 seconds but he never goes above 59 minutes 8 seconds a day
Venus - 59 minutes 8 seconds.
Mercury - 59 minutes 8 seconds.
Luna - 13 degrees 10 minutes 36 seconds a day.

Scroll down almost at the bottom is a section on Partile and Platic aspects.
* "With cor leo, or spica virgo"
The fixed stars Regulus and Spica - if it is in conjunction with these stars, it is considered a dignity.
* Moon decreasing - does it mean a waning moon?
It means she is passing from her opposition(Full moon) to her conjunction(New moon) (as opposed to increasing which is her conjunction to opposition)
I should also note, that when considering Almutens, I rarely consider the Accidental dignities of the Planet, I prefer only to use the Essential. If there are two Planets competing for Almuten, then I will bring in the strongest accidental dignities to determine.

plus how do you determine occidental/oriental when the Sun is in Pisces...
The sign of the Sun doesnt matter, if the Planet rises before the Sun (remember the Ascendant is the horizon and rising point) then it is considered oriental, if it rises after the Sun it is considered occidental. An easy way to see this is to cast a chart, if the Sun is placed in the 5th House for example, and the other Planet in the 3rd then it is Oriental because it is closest to the Ascendant. Whereas if we find that Planet in the 8th, it is Occidental because the Sun is closer to the Ascendant and therefore will rise AFTER the Sun has risen.
I believe my Lord of Geniture is one of the malefics,Saturn(
Benevolent and Malevolent are interchangable terms, Jupiter can be just as malevolent as Saturn can and Saturn just as benevolent as Jupiter. It matters how they are placed in the figure and their influence. While Saturn is a natural malevolent, when found in abenevolent condition, his malevolence is abated.
----------------------
If your lord of Genitature is Saturn, then you will possess the characteristics of saturn, I presume it's both good and bad characteristics.
When Saturn is fortunate, he brings the good characteristics of Saturn, when he is unfortunate, he brings the malevolent characteristics of Saturn. All Planets have good and bad characteristics, and when they are fortunate they will always show the best side of the Planet. The degrees of this are considered by the strength of they are provided by their position. Someone will reap larger benefits from a Saturn in his House, than someone who has Saturn only in his Face.
