Ok, I think I got this thing working now.
I did not know how to extract content A,B,C from "only" end brackets so I had to create new VAR from the tail brackets (if existed) and then extract contents of A,B and C from that. Otherwise regex would be getting 1,2,3 from brackets in the filename.

Anyway... it is ok as it is now but if there is a better solution I would love to learn it.
note: this is for string testing only, once it is in a real script I would have checking to see if file or directory before getting shortName and extension.

Code:
#!/bin/bash
test_str=(
    'test1.{1}(2)[3] dots.spaces {A1}(B1)[C1].ext'
    'test2.[3]{1}(2) dots.spaces [C1](B1){A1}.ext'
    'test3 [3].com [C1].ext'
    'test4 {1}(2)[3]dots.ext'
    'test4 {1} (2) [3] dots.ext'
    'test6 (B1)[C1].ext'
    'test7[C1](B1).ext'
)
IFS='
'
regexp='\s*(\([^)]+\)|\{[^}]+\}|\[[^][]+\])+$'
subst=""
regexTag='.*\[([^]]+)\]'
regexLab='.*\{([^}]+)\}'
regexDes='.*\(([^)]+)\)'


for p in "${test_str[@]}"
do
    NameNoExt=`echo "${p%.*}"`
    if [[ $NameNoExt =~ $regexp ]]; then
        tailBrackets="${BASH_REMATCH[0]}";
        shortName=$(echo "$NameNoExt" | sed -r 's/'$regexp'/'$subst'/g');
    else
        shortName="$NameNoExt"
        tailBrackets=""
    fi
    # if tail bracket exist then extract A,B,C
    if [ $tailBrackets ]; then
        if [[ $tailBrackets =~ $regexTag ]]
        then 
          TAG="${BASH_REMATCH[1]}"
        else 
          TAG=""
        fi
        if [[ $tailBrackets =~ $regexLab ]]
        then 
          LAB="${BASH_REMATCH[1]}"
        else 
          LAB=""
        fi
        if [[ $tailBrackets =~ $regexDes ]]
        then 
          DES="${BASH_REMATCH[1]}"
        else 
          DES=""
        fi
    else
        TAG=""
        LAB=""
        DES=""
    fi
    zenity --info --text "`printf "Filename = \"$p\"\n\nNameNoExt = \"$NameNoExt\"\nShort Name  = \"$shortName\"\nTail Brackets = \"$tailBrackets\"\nA  = \"$LAB\"\nB  = \"$DES\"\nC  = \"$TAG\""`"
done

gammu-smsd-files

GAMMU-SMSD-FILES(7)						       Gammu						       GAMMU-SMSD-FILES(7)

NAME

       gammu-smsd-files - gammu-smsd(1) backend using filesystem as a message storage

DESCRIPTION

       FILES  backend  stores  all  data  on  a  filesystem in folders defined by configuration (see gammu-smsdrc for description of configuration
       options).

RECEIVING OF MESSAGES

       Received messages are stored in a folder defined by configuration. The filename will be IN<date>_<time>_<serial>_<sender>_<sequence>.<ext>,
       for example NN20021130_021531_00_+45409000931640979_00.txt.

       Explanation of fields:

       <date> date in format YYYYMMDD

       <time> time in format HHMMSS

       <sender>
	      sender number

       <serial>
	      order of a message (in case more messages were received at same time), in format NN

       <sequence>
	      part of the message for multipart messages, in format NN

       <ext>  txt for text message, 8-bit messages are stored with bin extension, smsbackup for gammu-smsbackup

       The content of the file is content of the message and the format is defined by configuration directive InboxFormat (see gammu-smsdrc).

TRANSMITTING OF MESSAGES

       Transmitted messages are read from a folder defined by configuration. The filename should be one of the following formats:

       o OUT<recipient>.<ext>

       o OUT<priority>_<recipient>_<serial>.<ext>

       o OUT<priority><date>_<time>_<serial>_<recipient>_<note>.<ext>

       Explanation of fields:

       <recipient>
	      recipient number where to send message

       <priority>
	      an alphabetic character (A-Z) A = highest priority

       <ext>  txt for normal text SMS, smsbackup for gammu-smsbackup

       <note> any artibrary text which is ignored

       For text messages, you can additionally append flags to extension:

	  d	 delivery report requested

	  f	 flash SMS

	  b	 WAP bookmark as name,URL

       Other fields are same as for received messages.

       For example OUTG20040620_193810_123_+4512345678_xpq.txtdf is a flash text SMS requesting delivery reports.

       SMSes  will  be transmitted sequentially based on the file name. The contents of the file is the SMS to be transmitted (in Unicode or stan-
       dard character set).

       The contents of the file is the SMS to be transmitted (in Unicode or standard character set), for WAP bookmarks it is split on as Name,URL,
       for text messages whole file content is used.

       Please  note  that  if file is not in Unicode, encoding is detected based on locales, which do not have to be configured if SMSD is running
       from init script. If this is your case, please add locales definition to init script.
