weather-king forced air gas furnace a/c questions

Hey guys new to this forum,
I have just bought a new 2 fl home with a weather king 125,000 btu forced air furnace a/c installed and have some questions.
I have 2 returns in the house on centrally located on the first floor on a wall large in size aprox 18 x 18, the 2nd on the ceiling in the 2nd floor hallway aprox. 16 x 16, (doors on the 2nd floor are cut 1/4 to 3/8 short to allow for return air escape the rooms and go to the returns - this is what I was told) rooms have 2 registers one high and one low for heating / a/c. The T-stat has been replaced with a LUX TX500 digital / programable. all components in furnace are set from factory.
The questions I have are as follows:
1. the t-stat clicks when it turns on and off.
2. a blast of cold air comes out of the ducts before warm air ( I read to lower blower setting it is currentlly set to med for heat and high for a/c.)
3.can the returns be filtered in conjunction with the blower compartment or will this choke the system ( blower compart. filter replacement has been difficult due to unique size 22 3/4 x 25 )
4. Any ideas as to why the bathroom register trickels out any air. duct has been checked for blockages and is clear, the amt of elbows/ bends to bath are unknown.
5. Can this system not have any dampers I could not locate any by furnace area most of the duct work is behind sheetrock.all registers are adjustable
6. register, furthest from furnace blows like a tornado why?
any help to these questions will great!
BDR

1. normal, points inside tstat are making/breaking
2. possibly a setting at the furnace, on circuit board
to adjust time delay on... increase the setting
3. you can filter at the grille (some are made for this)
OR at the unit, 2 filters is usually too restrictive.
a filter rack with common filter dimensions should be
easy to install
4. location of tap from trunk or break in duct possible
5. well over 50% of systems i see have no dampers.
check the takeoffs that you can access. if there are
none there i would not expect to find any elsewhere
6. if it comes off the endcap of the trunkline it is will get
a lot of air, disrupting static pressure inside the duct
not allowing branch ducts to "get their share" of airflow
