My team has been using a speacial sin curve array to tone down the sensitivity. It has kind of been a hand-me-down for four years now.

const rom unsigned char joystick_values[256] =  {  
0,   0,   0,   0,   0,   0,   0,   0, // 0   - 7
 
0,   0,   0,   0,   0,   8,  16,  24, // 8   - 15
     
30,  36,  41,  45,  50,  53,  57,  60, // 16  - 23
    
63,  65,  68,  70,  72,  74,  76,  78, // 24  - 31
 
80,  81,  83,  84,  86,  87,  88,  89, // 32  - 39
    
90,  91,  92,  93,  94,  95,  96,  97, // 40  - 47
  
98,  98,  99, 100, 101, 101, 102, 102, // 48  - 55
 
103, 104, 104, 105, 105, 106, 106, 107, // 56  - 63
  
107, 108, 108, 109, 109, 110, 110, 110, // 64  - 71
  
111, 111, 112, 112, 112, 113, 113, 114, // 72  - 79
   
114, 114, 115, 115, 115, 116, 116, 116, // 80  - 87

117, 117, 117, 117, 118, 118, 118, 119, // 88  - 95
 
119, 119, 120, 120, 120, 120, 121, 121, // 96  - 103
 
121, 121, 122, 122, 122, 122, 123, 123, // 104 - 111
  
123, 124, 124, 124, 124, 125, 125, 125, // 112 - 119
  
125, 126, 126, 126, 126, 127, 127, 127, // 120 - 127
   
127, 127, 128, 128, 128, 128, 129, 129, // 128 - 135
   
129, 129, 130, 130, 130, 130, 131, 131, // 136 - 143
     
131, 132, 132, 132, 132, 133, 133, 133, // 144 - 151
     
133, 134, 134, 134, 134, 135, 135, 135, // 152 - 159
     
136, 136, 136, 137, 137, 137, 137, 138, // 160 - 167
     
138, 138, 139, 139, 139, 140, 140, 140, // 168 - 175
     
141, 141, 142, 142, 142, 143, 143, 144, // 176 - 183
     
144, 144, 145, 145, 146, 146, 147, 147, // 184 - 191
     
148, 148, 149, 149, 150, 150, 151, 152, // 192 - 199
     
152, 153, 153, 154, 155, 156, 156, 157, // 200 - 207
     
158, 159, 160, 161, 162, 163, 164, 165, // 208 - 215
     
166, 167, 168, 170, 171, 173, 174, 176, // 216 - 223
     
178, 180, 182, 184, 186, 189, 191, 194, // 224 - 231
     
197, 201, 204, 209, 213, 218, 224, 230, // 232 - 239
     
238, 246, 255, 255, 255, 255, 255, 255, // 240 - 247
     
255, 255, 255, 255, 255, 255, 255, 255  // 248 - 255
};

It's worked for us. Just put the array like this:

pwm_01 = joystick_values[p1_y];

Do this for all pwm's you want dampend. Hope it works.

As for limiting speed, I have no idea what the arguments of the Arcade function are. If set pwms are what you are using to change the pwm values, they are commented out (you probably know that already). You also have it set 177 on the 77 if statement and 77 on the 177 if statement. Would switching those two help?
