BlackGuard Int 8 Wisdom 14 the rest maxed- does his spell casting suffer later in BG2?

I made an angry Black Guard who does not get along well with others...
Question: Can he cast all the Paladin spells in BG2?.... Will he get less spells with the low wisdom score than an 18 wisdom Paladin? Will an EIGHT Intelligence matter?
Game starting Stats that took an hour to roll up while listening to a podcast....
Str 18 (71) (he was taking some funny treatments from a mad doctor in the crypts with Lance)
Dex 18 (he dodged many goodly nunnery nuns justified rod beatdowns)
Con 18 (his head became inured to all the injurious head banging he did in blackminded rages)
Int 8 ( he did not study at the covenant his mama abandoned him at)
Wis 14 ( he became wise from reading tomes in Candlekeep when he was not at the nunnery)
Chr 18 ( he learned to be magnanimous from cute little Imoen)

Just like a paladin, wisdom doesn't do shat for your spell casting.
10+ int would've been better...mindflayers are nasty.
Swap int and wisdom and he'd have nice stats. After the manual and lum, you could take 3 regular mindflayer hits before dying.

Paladin = lv 9
This Black Guard is going to Own the Battlefield when he casts Clerical Draw on Holly Might and the other 5th or sixth level ones... I forgot the name but I recall it buffed a certain weak and stamina missing elf lass to a massive 25 strength and big con score in BG2.... I have forgotten the level name of it - not Champions strength - that is a limiter if you have an already buffed strength score... I can not recall the name of it - I do remember being impressed that the weak clerics buffed like Juggernauts with it and a combo of draw on holy might... I know I seem like an awful powergamer - but I did play for quite a bit with a very low Constitution turnip lover and one fireball shot slain whose of a thespian... but I could never force myself to play a Grey Mouser Swashbuckler....
SO a bit off topic and forgive my Munchinkin Power Gamer tendency but....
QUESTION: In BG2 Enhanced---
Can I play a regular fighter to level 7/8 or 9 and then duel class him to a Swashbuckler? (the Grey Mouser) or an Assassin? (Arti the Drizzit Bane)
Yes, you'll be two-shot by mind flayers with less than 11 in intelligence.
