Yes if all the bolts come off. No if they don`t!
I did it and could have done the entire job in a day easily, except for the lower long bolt that had seized into a bush. Horror ensued.
It's common for these long bolts to seize so I suggest that you spray plus-gas or WD40 all over every nut and bolt you can find for a few days and then try to crack nuts and turn bolts (that includes droplink bolts). If you can do this for all bolts (especially those long ones) then you should be ok. If you have any which are stuck then at least you don`t yet have the car in parts and can decide if you want to go to a garage or keep on at it yourself.
I have pictures of when I did it. As I said, when the lower bolt was seized it led to a sorry tale of new suspension arms, new droplinks and even the entire suspension beam needed to be dropped.
I posted this message not long afterwards which may help you. As I said, I have pics of various bits if you want them.

Don`t let me put you off too much, I was unlucky but you may well have a better time than me - my car is a 98 so the bolts were pretty firm! You can check if you are going to able to do the job yourself without actually committing to going too far as its commonly just one particular bolt that is a bit stiff (ha!). It’s the very long lower bolt that holds the transverse arms onto the bottom of the strut. Spray constantly with WD40 for days before starting. You will probably have no real difficulty in cracking the nut with a breaker bar (don`t even bother trying without a breaker bar, preferably a 24" one as a minimum - should cost well under a tenner) but its whether the long bolt is free turning or not that determines if you are going to have difficulties. On mine, one side was completely locked up and eventually sheared, but the other side was no trouble at all.
Crack the nut, try to turn the bolt and if it really wont turn, then decide if you want a garage to do the job. As to price, ask an Alfa dealer what they would charge you and go for the menu price. Its more expensive by the hour but if there are any problems such as your newly discovered seized bolt they can still only charge the menu price
Consider the slightly higher initial price as a type of insurance
To get the strut assembly of the car you undo all of the bottom bolts and the anti-roll bar connection and detach abs sensor and brake lines, but its the top that is different to what you are saying.
You have to undo 1 or 2 x 22mm nut on the top of the strut to release it from the car, depending on your method. The first holds a large top metal disk/plate in place and you must remove this in-situ. The second holds the strut into the upper rubber/metal mount. You can remove the strut in one piece and take the mount of afterwards but why bother unless you are replacing the mount. You say that you want to but I`ve seen a few so far and haven`t yet seen one that looks knackered. I just left the mounts in place.
Undoing the mount nut will release the spring. In my case I have slightly lowered springs so by the time I got the nut of the spring was loose and not under pressure, hence no spring compressor required. If you have standard springs there may still be some pressure but it won`t be much. It up to you, but do be safe. When putting the top mount back on, or when putting the strut back into the car when you haven`t taken out the top mount, some small compression may be needed so having a friend around helps to pop on the top nut a few turns (or alternatively put on a spring compressor).
This is 'secret tool' bit. To take off the nuts from the top of the strut you need to insert a 6mm Allen key into the top of the shock rod to prevent it spinning whilst you undo the nut. This is physically impossible to do with a normal socket or a spanner and Alfa use a 'special tool' to do it. The secret tool workaround is a lambda remover, or a diesel injector remover. These are 22mm, very deep sockets with a large window cut out of the side of them. You can get them onto the top nut and put the Allen key through the window and voila! I recommend a long Allen key for decent leverage. Be warned that not all of these special sockets fit as some have sidewalls that are too thick to fit into the mount. On the plus side most motor factors have a choice and when I get home I can see which one mine was if you like (I think its a Volvo diesel injector remover one but can`t remember). I recommend that you uncover the top of the strut and drive to the shop so you can try a few ones out for fit before buying. They should set you back about £7.
