You should go for an XL engine, and a large one too. The extra speed on your LRM cat is worth more than you might think. I use an XL300, endo, and only 12 DHS (just the two in the engine) to save weight and crits. I would advise keeping the 4 jumpjets too, mobility is king.
Then you should also get artemis, and probably drop the LRM10's for LRM15's. You have the spare tonnage now, and with artemis the missiles get a serious buff so deserve more focus. Ammo is up to you, but I bring six tons.
I assume you use your MPLS for self defense? You can drop them to MLAS without much worry. If your using your self defense weapons, things have already gone wrong. Or you can drop a couple of them altogether and get more interesting things. I run MLASx2, ERLLAS, TAG. I can't live without my ERLLAS now, but TAG is less and less useful all the time and I may drop it soon for more armor.
Speaking of armor, with an XL engine your side torsos will be weak spots, so shuffle your armor around to protect them. I used to use an extra ton of armor (352), and that was a lot better, but 320 is still ok as long as you distribute it properly. But as I said, I may ditch the stupid TAG soon if it doesn't start actually helping.
Good luck with your C1 building! It's a sturdy and surprisingly versatile mech, and excels at a number of roles. And if you get bored with LRM boating (you won't, it's awesome), you can always slap on some SRM's and some stronger lasers and try your hand at cat brawling. The torso twist is a bonus, the massive face, less so.
