1 - The PP - stripped down won't make difference too much, is a huge ship - go for armored or OC - you will need every drop of juice for those huge hard points....
Engine - go for Dirty & Drag drivers, so you can dance circles around Annies ; And the PD I advise you to modd him for WEAPONS... make a HUGE difference in battle !
2 - Instead of hull reinf. packs, go for GSRB - the Vette enjoy a great shield multiplication, like the Annie, and you can easily get in the 5-7k range - so you will NEVER loose shields battling NPCs ; Then, what is the point of reinforcing the hull ?! And adding the extra weight ? ....
3 - instead of FSD interdictor ( kind of useless , since all small/medium ships are faster than you...) - I suggest taking an AFMU , so you can repair some scratches in the field, without the need to doc somewhere for repairs.
4 - ditch BOTH of SCBs - you wont need ANY of them at grade 7 battling NPCs ! - put, instead, a cargo bay in those slots for your limpets who will harvest materials from your victims, and on the other put a class 7 Collector - so you will have a cloud of limpets after you harvesting when you kill NPC after NPC.Also, this will give you some extra flexibility, for short cargo runs as a heavy armed transport, for those missions where you will be ambushed 5-7-9 times by Annies NPC. ( last weekm I got a mission to transport 96 tons of gold and I got not 3 not 5 but yes NINE ( 9 !! ) Condas Pirates dropping on me, one after one.... A FUN FEST OF KILLING - got more credits from bounties than from mission, lol ! )
5 - Add, in one of the class 5 internals, a SCB, engineered with Boss Cell, so you won't need to use any heatsink in your Utility slots - instead fill those slots with SB , one Wanted scanner, buffed for fast scan (2 seconds/scan) , a Point Def. turret, a Chaff - and all others SB. The SCB will rarely be used, I tell you this, if you do NOT make any dumb mistakes, you never need a SCB.... but have one class 4 or 5 with you, just in case, more for moral effect

6 - weapons wise - get 2 Beams grade 5 efficient with TV in those class IV HP.s, so you can cook fast any medium//small NPC, and all the rest go MCs ; But do not ruin the perfectly placed class IV hard points with mixed weapons....
7 - Add a class V hangar and get a good NPC pilot ( you can train one from scratch, like I did, to save many millions of credits later, or you can just "rent" an elite one, before you go fighting.... Anyway, it will be like another class IV long range weapon for you, and will bring you a serious buff, both in attack and defense.
When you get all this - will be no NPC who can stand your firepower , in a 1 vs 1 , and usually you can take on 2 wings of normal
NPC s at once, without any problems.
