Specialized Allez Fork and Headset Advice

I'm planning a spring overhaul/upgrade for it my Specialized Allez 16 2014. Upgrading to 105, new wheels possibly some narrower bars and maybe a carbon seatpost. Not upgraded anything prior to this other than a set of Conti 4 Seasons and replaced the chain and a cable after it shredded to pieces inside my shifter.

Whilst I'm upgrading bits and pieces I was considering my fork and headset. The fork is aluminium and I don't find the ride overly harsh but it is sometimes a bit rough. I'm trying to increase my distance on weekend rides at the moment, not sure if upgrading the fork would be noticeable/worthwhile in terms of comfort?
Looking at a couple of 1 1/8 forks available like the Ritchey and Tifosi linked below they both have a rake of 45 mm whereas the geometry chart here

says that the fork on my 54 cm frame has a rake of 57 mm, that seems like a pretty big difference.

Would either of those be compatible and is it even worth upgrading it? Or just not worth the hassle?
With regards to the headset would it be best to take it out and inspect/clean and then regrease it? Any obvious signs it would need changing? I haven't noticed my steering being particularly bad or anything so I assume it's all good.
Have tried to find out from googling what I could replace it with if needed. Would either of these fit?

I know there's the new bike option but I'm planning to upgrade this bike and continue to use it as a commuter/year round road bike then save up until I can afford something considerably nicer. I have also considered picking up a frameset to replace it but I don't know whether that would actually be worth it just for a carbon fork. I'm under the impression the allez frame is pretty decent anyway. Even if I did get a frameset, unless I bought second hand (which I don't mind), It's probably not within my budget at the moment when I add together all the upgrades I'm considering, e.g wheels, groupset, also some new shoes... all tots up
Any thoughts and advice appreciated!

What’s your budget - all parts Inc cables, tools you may need to buy, ny work that needs doing at shops?

I’m fairly flexible budget wise. I’ve already picked up some wheels and I’d say for all the other components and tools to try and keep the cost below £700.
or just go the Spesh shop and ask for some. Or take yours in to any shop and match them up.no need to make life complicated.

I'm not sure I'd spend £700 on the Allez TBH - for only a little more you'd be better off getting a new 'best bike' with new, 2018 spec/components and using the Allez as a winter hack.
This.

Obviously I don't know what level you cycle at but for the average Joe I have to question if the "gains" are proportionate to the outlay.
I use my Allez for winter and poor weather riding but I love it. Such a capable and good frame.
As for the forks, you may be able to get a pair of allez ones on eBay etc
I have an Allez (2013) and it is a fantastic bike, Fast, Strong, Reliable. Full disclosure, I did upgrade the wheels but I can take those anywhere.
Cheers
