OK. Reverse engineering:

Bluff: +16 (+13/r +3/cha)
Disable Device: +10 (+8/r +2/int)
Hide: +17 (+13.5/r +4/dex)
Move Silently: +17 (+10/r +3/fam +4/dex)
Open Lock: +15 (+11.5/r +4/dex)
Perform: +13 (+10.5/r +3/cha)
Search: +12 (+8/r +2/int +2/racial)
Sleight of Hand: +10 (+6/r +4/dex)
Tumble:+10 (+6/r +4/dex)

In 4e this is training in Bluff, Thievery, Stealth, Stealth again, Thievery again, N/A, Perception, Thievery again, and Acrobatics or even just a couple of good shift powers.

Which means Bluff, Stealth, Thievery, Perception, Acrobatics. You'll be more generally competent anyway - Perception also covers Spot and Listen for one. Any reasonably sane class can do this. (For a barbarian it would be a challenge).

cantrip.- Ghost Sound, Light, Detect Magic, Mage Hand, Flare, Message, Open/Close
1st.- Instant locksmith, Tenser's floating disk, Comprenhend Languages, Detect secret doors, Silent image
2nd.- Knock, Invisibility, Spider Climb
3rd.- Fly, Shrink Item

Your cantrips are, alas, cantrips. The nearest I can do is the Wild Talent feat which is technically Psionic, but who cares?

Your first level spells are almost all rituals with the exception of Detect Secret Doors (Perception skill covers this) and Silent Image. You just need one of the dozen or so ways of getting Ritual Caster.

Your higher level spells are either Rituals or Utility Powers. In 4e almost anyone can manage non-combat casting with the Ritual Caster feat and then use weapons in combat - and you have no non-combat rituals. You do not need an arcane class in 4e.

Feats:
1st.- Point Blank Shot
3rd.- Weapon finesse
Fighter 1.- Precise Shot
6th.- Combat expertise
Ranger. Track
9th.- Improved feint
Ranger 2.- Rapid shot
12th.- Multishot

Track just means you need training in survival. Weapon Finesse is thrown in with the power system - you just need to be a dex (or even cha) based class. Rapid shot and multishot aren't really how 4e combat works - no such thing as iterative attacks. And you don't need precise shot for 4e.

Unarmoured Agility is technically a waste of a feat, but keeps your AC competative.

This leaves us with just the classes to handle. 4e has precisely one class that can multiclass out to everything - and that's the Bard - and Bards can be mostly martial and get the ritual caster feat. But we can do one better than that with the Traveller's Harlequin Paragon Path from Dragon 382, allowing you to be a thief or twin striking ranger (your choice depending how important rolling two attacks is) as your primary class. And both thieves and rangers have serious combat mobility.
