Response Spectrum Analysis STAAD Pro - URGENT

My question is regarding carrying out a response spectrum analysis in STAAD Pro. This is what I have done so far.

I have set up the model in kN and METERS units. I have allowed for the joint weights in the form of udl loads on the beams in all three X Y and Z directions(should these be global or local??) for the two orthogonal directions X and Z. I have created a custom response spectrum using period and acceleration calculated from clause 11.4.5 of ASCE 7-05 with a damping ration = 0.05.

The values that I used for generating the response spectrum are as follows:

S1 = 0.3, Ss = 0.7 giving Fa = 1.24 and Fv = 1.8

Sds=0.58, Sd1=0.36, To=0.12sec, Sms = 0.87, Sm1=0.54, Ts = 0.62sec, TL = 12secs

My input spectrum looks like this:

SPECTRUM SRSS X 1 ACC SCALE 1 DAMP 0.05 LIN MIS
*RESPONSE SPECTRUM X
0 0.23; 0.05 0.37; 0.1 0.51; 0.15 0.58; 0.2 0.58; 0.25 0.58; 0.3 0.58;
0.35 0.58; 0.4 0.58; 0.45 0.58; 0.5 0.58; 0.55 0.58; 0.6 0.58; 0.65 0.55;
0.7 0.51; 0.75 0.48; 0.8 0.45; 0.85 0.42; 0.9 0.4; 0.95 0.38; 1 0.36;
1.05 0.34; 1.1 0.33; 1.15 0.31; 1.2 0.3; 1.25 0.29; 1.3 0.28; 1.35 0.27;
1.4 0.26; 1.45 0.25; 1.5 0.24; 1.55 0.23; 1.6 0.23; 1.65 0.22; 1.7 0.21;
1.75 0.21; 1.8 0.2; 1.85 0.19; 1.9 0.19; 1.95 0.18; 2 0.18; 2.05 0.18;
2.1 0.17; 2.15 0.17; 2.2 0.16; 2.25 0.16; 2.3 0.16; 2.35 0.15; 2.4 0.15;
2.45 0.15;

My question are:

Based on the input of acceleration v period what should my scale factor be? Scale =1 or Scale = 9.80665???
My mode shapes look the same for each direction X and Z for each mode. That is Mode 1 of X looks the same as Mode 1 of Z. Is this correct? see below.
How do I check that my modal base reactions are correct?
