Grots are good screens, but make sure they are small squads as they are likely to run away. Boys are good screens too, as they can be fearless and hit harder. Grots are very good objective holders, which is what you typically see them used as.
The rest of your advice on this thread is pretty solid, But I would recommend larger grot squads. They are 3 points per model. A mob of 29 (so you don't have to buy the 3rd herder) is 107 points, 19 (for just one herder is 67). It takes 8 kills to make a
LD check with a mob of 29 (not hard, but probably more than one unit shooting at it to do this) or 5 for a mob of 19.
LD is tested off of best
LD, which is 7, which passed slightly more than half of the time, but at the cost of d3 grots (squig hounds) can be rerolled. Grots don't run away from shooting too often. A small squad just means that it will be easier to force morale (min squad size requires just 3 kills), and they won't have numbers to absorb shooting casualties and re-roll attempts (small squad, 3 kills to force morale, d3 more dead from re-roll = mostly dead squad).
If you go with the full 30 + 3 herders, it requires 9 dead to force a morale check. If you have a
KFF near enough (with large squad of guys screening not too difficult) that requires on average about 24 bolter shots, which is at least 12 marines, which is almost double the points of a full grot squad. Template weapons of course would be better, but it still is quite a few shots with them to force anything (unless it ignores cover... then you are screwed as normal with orks)
