Bike trouble

IVE been advised on here to get a pressure test as some of the things i have posted sounds like the head has gone,
I rang a local garage today and they said the nearest they can get me in is next thursday for a pressure test how stupid is that,
so i went for a little ride till next thursday and a whole load of sh*t was happening (sorry for the language but i thought the biggest problem was gonna be passing my test now its turned out to be this japanese bitch :smt013)

Problem number 1, there was a little lack of power she had warmed up but when i pulled the throttle back she was taking a bit to pick up the speed this never used to happen was ok when it hit 4k revs went up a bit faster.

Problem number 2, i could be sat there and the heat gauge was a half a centimetre from the red then as soon as i moved it would be quarter of the way up even when i was riding sometimes it would shoot right up.
And i never heard the fan kick in when it was up.

Problem number 3, it was struggling to start when i knocked it off, one minute it would sound like there is no life in the battery the next it would try and fire up, and after a while it would fire up

Problem number 4, a lot of steam is still coming from the expansion bottle over flow pipe sometimes when am riding but mostly when i pull up and knock her off.

Now im hoping the head gasket has gone and that is why im getting these problems, should i just replace it anyways ive heard you gotta do them every so many miles anyways, also should i replace the cam chain whilst i am doing this ?

I have got a clutch gasket, new spark plugs, oil filter, oil and a clutch plate im going to buy a head gasket but that could be next week will it do the bike any damage if i dont have any oil in it until it arrives because it wont be worth putting the new oil in it until the head is done or am i wrong ?

I just dropped the oil outta me bike, its black isnt it meant to be black with white gunky bits in it if the head has gone ?
cheers

Sorry for babbling on and being a pain in the butt and thanks for the help

Just an update ive just checked to see if there was water in the radiator and there was under a cup full i only filled it up right to the top on the 13th of september, i know it should be topped up now and again but that seems a piss take, it had an mot advisory for coolant leak but i cant see no where where the water is leaking out from when i fill it up. Any help how i can find where its coming from ?
My bike is a zxr 400 H 1990 model if that helps

Also just above where the oil filter goes, is it the engine block where it connects, and its kinda like split into different parts (hope this makes sense) well the seal or joint thingy lol, just above where the oil filter is it looks like oil is seeping out, i think its coming out very very slow though because i cleaned it all about a month n half ago and theres not much on it about a 7cm by 7cm patch where its ran down is this something to worry about ?

thanks

The coolant could be going into the engine, i had this problem with an old motocross bike with the head gasket gone, and it meant abit of power loss as well.
